Re: Foils Layup

[Christian Rasmussen <Christian@xxxxxxxxxxxxx>]

Bill,

You really dont want to use any kind of kevlar (straight or hybrid) on 
the foils. Its a pain to do anything with unless
you can create the foil into its final finish. Any sanding on kevlar 
will turn into a teddy bear real quick. I would suggest
using all carbon and added up it should be about 25-28 oz. E.g 4-5 
layers of 6 oz carbon fabric is good.
