What is the latest with the RDM vs SDM pros and cons?

Is pretty much everyone using RDM for wave-sailing?

Does every pro use RDM in their wave sails?

I would like to buy a new 400 mast but it will only work with a few sails 4.7 and 5.3, but at least with the SDM, I could buy an extender and then use the same mast for a 6.2.

plenty of previous posts on this, try a search.

I'm generalising, but most or all wave sails now are designed to rig on RDM, they 'accept' a SDM fine,
although are theoretically more efficient on a RDM.

I didn't convert to a RDM that long ago, I was surprised how responsive the (wave) sail was. Some sailors -
mostly the heavier guys I've noticed - like the stiffer feeling of a SDM. Visually sails can appear to rig better
on a SDM.

I think larger and cammed sails may be more suited to a SDM, that's a bit of personal preference I guess.

It depends on your quiver and type of sailing. I have a 400 mast which rigs on 5.4/5.1/4.7 & will rig on a older
model 4.5 but most newer wave sails from about 4.7 down will use a 370 which is 'softer'.

Check the mast compatability chart as a guide, but usually best to have same brand sail & mast.

SDM masts in waves sails are about as obsolete as that cigarette lighter some idiot installed in my car that I use to charge my phone..

My phone is hardwired into my car. Is yours portable or something?

Been waiting for another Barn Paint
Gold

Love the 3 cop cars in the rear view mirror

But - you have a B&M shifter in a VW?

Barn, only 3 cops in 'pursuit' for a phone out of the craddle, how slack!

Please do a cartoon for a SDM on a wave sail (with a VW van somewhere in there of course)...or not.
