"He who marches out of step hears another drum." ~ Ken Kesey
On a team run of 12, I would probably go for the cad-cut, but that's me. As for them bleeding, they can, never happened to me, but I've heard of it. For known bad bleeders (or likely suspects), there is a Subli-Block from Specialty Materials. except that for Dazzle and misture wicking Poly, they recommend their "Extra" which is the choice for Nylon.Siser, as far as I know, has no specific bleed resistant film, but also lists no limitations on type of poly.If you decide to go heat seal, try to talk to a tech and get their take on it.Steve, did the shorts melt in the dryer, or on a heat press?
