not to seem critical, but,
i doubt youve ever rode karmas they are actually really good for the park maybe a little stiff but thay actually pop pretty nice. but in my opinion i think if all you want your new stix for is park id get t-halls. thats just me though. but it seems like your a big guy so you might not wnat a couple wet noodles on your feet and want something a little stiffer and so karmas actually might be pretty sick for you/\.
