i have talked with dave back in 2001. he said that his west coast folks demanded ____, therefore he was going to provide them with _____. this was when jason voss and i were sailing a 8.5 infinity at the board test in maui. and we asked him to provide a 490 SDM. he came back with a 490 skinny. the sail felt worse to us. after he left, i put a 490 SDM in his sail, and it was WAY better. so, he acknowledged what we said in a very back handed way.

fashionistas ruled way back then too. head to head testing was way easier back then, we had 150+ sails to play with. i did the same kinda stuff in later years here in FL. it helped me stay interested in testing gear. i learned a bunch by doing so too. scientific method trumps everything else.

I went and asked David, and he says:

"An SDM has the potential to be lighter weight, because the wall thickness of an SDM is less than an RDM. This is especially noticeable on a 490."

I also have a Aerotech Phantom 7.5, so I thought I would see what Steve would say. He responded:

"SDM will be much more stable and will give more control and speed. The RDM will have a bit more low end power and will pump onto a plane slightly sooner. For flat water and small surf i prefer the SDM. For waves I like the security of the RDM."

Anyways, I have my answers now...thanks guys.
