First off, dont kid your self, talkin like a 3rd person, just say you need help pickin a board... the way you type is kinda weird,
you seem to know alot about snowboarding then more parent do, and 2nd you dont even mention their age or weight or nething that really relates to your sons.. im assuming they're full grown kids? altho i hope there not but all wells some ppl are mamas boys for ever, neways... if your kid is gonna jib all or more then %90 of the time, u dont need to spend xtra $100.
and gnu street series more stiff then subpop and is more of all around then subpop, where is subpop is pretty much noodle that doesnt have even decent amount of pop <--- (ask what pop and noodle is to your kids they'll tell you)
lastly i dont even know why im replying to this??? seems like your kids should know a thing or 2 about boards, if 1 of your kids loves jibbing so much just ask your kids what they want, instead of asking ppl online?????????????? im still skeptical about you.. :/
