though i think your right it would be a bitch trying to play with all the pros, but on the plus side, they would prob mass produce things like lavers, quatums etc, and at a lower price becasue more are being produced.
also fabric shops are more likley to supply USL because people will be in greater demand for it, and people will know what the hell it is! (sounds crazy but i went into a fabric shop in eng, askd the person if they had any, and the guy asked me what is was!! IN A FABRIC SHOP?!?!) so you would be able to get hands on material easier.
yes the chance are you may not be able to play with the pros as much, BUT there a chance alot moe people would play in your area because of the sport being known world wide. and lets face it, alot of threads on here are of people asking "does anyone play in or near....." so i dont think it would be so bad becasue you will have new people to play with, and less chance of people giving up because i thought they were on there own, so i think the benfits out way the set backs!
that my humble opinion.
