is there any difference between youths 142 and adult sizes? i am 5'2 and 115 lbs adult. but i am afraid youth sizes are not as durable or the same as adult sizes. i remember reading from the never summer uk site that last years 142 evo only has standard camber tech and seems to lack the vario grip vs. the adults r.c tech vario grip system. if that is the same as this year then i would much rather get the 148. anyone can give me any advise?
