I was reading about a surfboard called "Futue flex", it uses a quad axial glass fabric for lamination. I understand this means one of each 0, 90, 45 and -45. I have two questions:

1) Would it matter if I used UD 0,90,45,-45 or if I used woven 0,90 and +45,-45. My question how would it differ if I used UD vs woven, I understand that UD has less crimp and less resin rich regions, does it also have any effect on the mechanical properties?
2) If I understand correctly, 0 & 90 are used for longitudinal and transverse stresses, what are +-45 used for?
