cut of your jib

hope this may help, probably a bit of woffle but hey

when I design a sail I start with a designed shape then I produce panels over the mould kinda like when you plug a boat, then we choose a panel layout that flows over that shape thanks to our rather fancy software! when choosing radial layout over cross cut the weight of the fabric comes into play, lighter fabric is utilised when orientationing the panels inline with the loads expected in the sail to help maintain the design shape
for smaller sails like jibs, cross cut tends to produce a super smooth foil, radial helps hold the shape better over time and higher loads

in the fourteen the radial panel jibs do tend to out perform cross cut in the higher wind range, but the loads are pretty high, somthing like the miracle I might prefer cross cut to smooth the shape through luff to leech

I treat every class of boat differently using the optimum panel and fabric option to suit the sailors requirements

ps when you say polyant you might be refering to polykote which is a finish added to the fabric to stiffen the finish or harden creating a more stable cloth
