Hi,
I am upgrading my windsurfing equipment. Currently choosing a new sail for GPS speedsurfing and slalom. Which sails you guys would recommend from this selection:
1) Ka Koncept 6.6 2009
2) Loft Sails Blade 6.2 2009
3) Gaastra Vapor 6.5 from 2007 or 2008
4) RS:6 6.2
I can find some reviews about Vapor and RS, but not much about this Koncept and Blade. Can you enlighten me?
hey
I ride ka 7.5 loft 6.3 and have rs6 5.4 there all great sails and fast
I think there will be a great deal of difference in the 6.2loft and 6.6 ka
and rs6
I find the rs6 very powerfull for there size ka on the money and loft you can sail them in much higher winds ie I've given in on the 5.8 cos the loft has such a great range
so i think its more to do with your collection and wind range u use most .
happy sailing 
All great sails, no problem there.
Any other opinion from me will be seen at totally biased so I will just let these results speak,

as lelos12345 said above all are good sails. one thing to think about is what mast you have or going to buy.
as far as results go I think you find they all perform very well.
I find the Blades are one of the easiest race sails to use but then im bias also .
For me the decision was made on ease of waterstarting, which I do a lot. I tried one RS racing and couldn't get it out of the water, so a narrower luff sleeve was a must. I tried a Koncept and loved the acceleration and forward drive, bought one and found it a dream to sail. It just about sails itself. I now have two Koncepts and am in the process of acquiring a quiver of them. They suit a variety of mast brands which helps too.
My team captain Lao Shi has one 7m Loft Blade, and hasn't sailed anything else since getting it. No doubt he will reply to your question singing it's praises. The blade seems to have a huge range requiring a smaller quiver.
I can't comment on vapors.
Blades all the way. Absolutely best sail on the market considering performance, cost and quality.
BTW - I'm not sponsored by Loft (unfortunately)
Choco,
Very true I suppose.
Henrik,
I should have added that I predominately sail in open ocean conditions (Slalom orientated as opposed to pure flat water speed) and have found the Blade to be much more powerful through the lulls and coming out of gybes. They are also very stable and (in a good way) have a soft feel which is excellent when you have to deal with my local conditions. The thing that really tips it over the line is it's build quality - near 100% monofilm sails have never been very appealing to me.
I know the speed purists (who sail very deep and on flat water) will find this advice sacrilege as the Koncepts seem to be the sail of choice for them. Horses for courses although I think I've found my "Black Caviar*" in the Blades.
I have an 09 6.6 Koncept and an 08 7.5 Koncept which the 2011 7.0 Blade has now unexpectedly replaced as it's range is pretty incredible.
Can't offer any advice on the Vapours or RS:6.

The Loft and the KA:s are both fast, but very different sails.
I would say that Loft is close to a Naish (more busy) and KA is more like an NP (a little dead, but still fast). I prefer the busier style myself.

Hi,
I am sure I will be considered biased with my advice on sails as well, but for me KA Koncept are brilliant sails because of a few things.
1 Rotation is fantastic
2. The luff pocket is not to huge
3. tuneability of the sails is fantastic
4 Durability is very good and the fittings and finish is very good.
5. Price point is good
6. No gimmicks on the sails, and they feel light and natural on the water and deliver high speed.
7. Draft is locked in extreme winds.
8. Range is very impressive my 6.6 works fantastic in 15 to 30 knots no problem.
I have used many brands of race sails eg North, Naish, KA in the end I find the KA Koncept is best for my style of sailing that I have found thus far. Off the wind the Koncept just behaves so well, and is competitive with every other brand. Reaching speed is very good. I sail in heaps of high wind rough water situations and find I just forget about the sail and concentrate on the finding the best path through the chop.
Mates of mine use the Severn Reflex and they look very nice as well.
Try and see if you can demo all the brands and then make up you own mind.
Best of luck and enjoy whatever you buy because they are all good.

Hi,
Tnx for replying. What is the windrange for Blade 6.2 and for Koncept 6.6 ?
Can these both sails take other suppliers masts also?
I have impression that Neilpryde RS:6 is a more vulnerable than Blade and Koncept. Is that true? In my country RS sails tend to get damaged often.
Have you considered a Tushingham x15?
Light, very tunable and great range. I use a 7m in 16-30knots, at the lower end they are easy to pump and the higher end stable and easy to pin down.
Mr Love recently told me:
"The Koncept requires a true Constant curve to Combi Curve mast. Masts that will work fine with the Koncept will be KA, Powerex, North, most likely Loft, Ezzy and Tushingham but I have no experience with them. I know people using Neil Pryde X6 and X3 who are happy but again I have no first hand experience with them."
I use an X3 on my 5.8 Koncept and it works nicely.
What about Blade 2008 size 6.2? I heard a rumour That Blades before 2009 are not that good?
I have an offer for a blade with 65% mast. Is that low content carbon OK ?
If you want a softer sail that's a lighter in the hands (compared to RS 6), then a NP RS Slalom may be worh looking at as well.
Can you guys comment on Blade 2008 size 6.2? I heard a rumour That Blades before 2009 are not that good?

Right now I have decided to go whether for Koncept 6.4 2010 or Blade 2008 6.2.
In 2007 and 2008 the 6.2 was probably the best one out of the range. I don't think this sail will disappoint you. The 65% mast should be ok. But to be honest, i have never sailed a blade with less then 100% masts.
