Since you're laying it up in the mold, axial cloths should work just fine.

I'm no composites engineer, but I would guess that you'd get slightly less strength with 10 oz. less glass. SWAG: You'd probably have strength roughly equivalent to 25 oz. or so of woven glass.

: oz triaxial at a 45 -45 0 degree bias, would equal about 3 layers of 10 oz
