What masts do you have in your mast quiver?
Need to choose a 2nd mast for my sails 4.7 (Gun McWave 07), (soon to be also 5.2,5.7 loft lip 08) and 6.5 gaastra matrix 04
Currently have a 460RDM, looking at prob a 400 or maybe a 430
4.7 = 413 (rec. 18-20 400rdm),
5.2 = 425 (rec. 400/19 rdm other 430),
5.7 = 442 (rec. 430/21 rdm other 460)
to 460-odd luffs
ALL WITH VARIO TOPS
Do I get a 400 and rig the 4.7 and 5.2 on it, and rig the 5.7 and 6.5 on the 460?
This right or get the 430?
Trying to minimise masts and cover all my sails but buying 100% RDM Loft masts so want good performance so well matched to sails too, if poss. (even how mine isn't equal yet, but no point spending money on crap gear for your hobby)
You could get the 400 and buy a 30cm rdm carbon extender for about $150, which would allow you to make your 400 and 460 into a 430 and a 490 respectively.
I've just ordered one from North (silver edition) and I can't wait to try it out!
This would increase your options, but 430 looks like the go, judging by the sails you mentioned.
If your existing RDM was an Ezzy, you could buy a 400 and make a 430 out of a 400 bottom and a 460 top 
Will that North RDM extension fit on all RDMs?
I like the Ezzy idea, but doesn't help me, would this work on my lofts?
Anyone do this on Loft RDM's? Or other non-Ezzy brands (ones that dont advertise compatability between diff bits, i.e: is this a possibility for mine?)
While it's expensive at the outset, having one mast of each not only allows you to keep more sails rigged at one time (helpful on days the wind is up and down) but of course the sails will trim better. And if you take care of them your masts will live through several sets of sails.
Unless money is really tight dont waste your time using incorrect masts, just bight the bullet and get the correct ones! Vario heads should not ever, ever be used! They force a sail onto the stiffest part of a mast causing it to not perform correctly. I would rather use a larger sail with the correct mast downhauled a bit more over a smaller sail with 30cm of mast sticking out the top.
So, dism, are you sure you want these Loft sails? If you go for an Ezzy sail and mast quiver, you'll be set for years and years...
Yup, love the loft sails (well everything i've read and seen), built as well as Ezzy but can go fast and wind wind range from looking around
So Loft RDM 100% in 400 or 430? Anyone?
Wetwilly - like your extenda idea to get a 7.5-9ish sail on a 460, instead of going back to the old SDM 490 (then maybe when skills up I can upgrade if this is letting me down)
Just to throw another spanner in the works,
Unless you really really need a 100% carbon mast, ide steer away from one and go with something around 75-90% carbon.
only slightly more heavy but much stronger and will last you long time
Sorry if you already know , but 100% carbon masts are prone to breakage at the worst time , just ask bender!
ive only had 3 masts in my time and one was a 100%, sure it was nice good response and all that jazz but lo and behold one day i was rigging up and pop no more mast
no warning no cracks just dead...
now i have a Powerex 430 PrePreg RDM 85% carbon mast and it is the shiz! i love it.
Rdms all the way!
No it was a 460 sdm , it had its fair share of use and i wasnt annoyed that it broke,
however it is well known that 100% carbon masts break easily.
It broke just under the ferrule on the bottom half.
