I do own a set of R5’s (5.1-6.2) and are thinking of getting a R7 7.0, speaking of which “Trousers” do you have any experience of SDM vs RMD on your 7.0?
Until this recent season I'd been sailing almost exclusively RDM on other brand sails and loved it. I'm a slightly lighter flat-water sailor at 70kegs and when I ordered the 7.0 asked for RDM but the shop talked me out of it and I ended up going SDM and so far have no regrets, except for the raft of RDM extensions and shims that have sat unused in my garage all this summer.
But from what I understand, you just need to buy a set of RDM cams (+ boom shim) and you're good to go. Are you asking because you currently rig your 6.2 on a 430RDM mast? If so, you might as well go RDM cams and use the same mast, unless you like to have them both rigged and need another mast anyway.
I have an unfounded suspicion the ODs (particularly the larger, heavier ones) might be marginally better on SDMs (their 'native' cams), but it's probably only detectable in the hands of a professional windsurfer, and the rest of us mortals wouldn't know. Anyone in the brains trust got a view on ODs on RDMs?
