Jib pattern: miter or crosscut?

Looks like I'll be stitching up a working jib for our SJ21. At 82 sqft, it shouldn't pose too much difficulty. The sail development software I have can accomodate all sorts of patterns, from crosscut to tri-radial. I've read for basic dacron headsails, the old-fashioned miter-cut jibs are really good, resisting stretch much better than pure crosscut sails.

Another advantage is smaller element size, which will allow easy template building. (I plan to loft the patterns on masonite rather than right on the fabric: will allow VERY precise layout, and repeatability if we need another jib.)

Wotcha think? Any opinions on cloth weight? We're very windy and gusty; looking at the 5.x oz high-modulus cloth. Overkill for a sail this small?

ETA: luff 20', leech 18.25', foot 9'.
