also... for all my shaped components, i used the 5oz hybrid tape. the tape is just thin strips of the material so you can make complex shapes better. this would be better for things like brackets, intake trumpets, etc.
i ended up using it for gaurds around cv's and bell cranks
And here is a link to a site that carries everything else. Marine quality and very good prices for about the best you can buy. including kevlar cloth in diff weights and bias. 5 oz x38" kevlar $16.95 per yard when buying only 1-4 yards and 5oz x60" for $24.95 per yard buying less than 4 yards.
Speaking of bias that is where you can gain alot of strength with less layers. Alternate your layers with the weave turned diagonaly in each layer so no matter which way you push or pull it you are fighting the weave not strecthing it.
