What is the spreader rake you have designed into these Carbon/Epoxy arms ?

Personally I believe that such a set-up can work well as long as the basic amount of spreader rake is sufficient and when at least you have some 30 mm adjustment range, preferably with 5 holes. (or more as long as it is an odd number)

Once you've found a good setting with the proctor arms you don't adjust them much anyway. So it all comes down to wether the designed of the boat has spend significant time to find the optimal setting for the sails that are sold with the boat. Sadly this is something that often gets cut in the race to get the product on the market quickly.

I'm still very happy with the Proctor arms and they weren't too expensive.

How much would these Epoxy arms go for ? Is there much saving in money ?
