they are awesome, and definatly a really really good park ski. they are light for their size, and easy to whip around, i can do 270's on to stuff just as easily as anything else, theres a little more noticable weight, but not much. for flex they arent as soft as people think, its more of a medium flex, it can butter and ollie awesome, but definatly not close to as soft as invaders. and they are super stable for jumps. its one of my favorite skis ive owned, and my favorite jump ski. when i was in the shop i was comparing the size to other skis, and the 179 was longer than other companies 182's and 183's. so its really around like 184, meaning a 189 would be like a 194 which is huge, the 189 was actually longer than a couple 190ish pow skis, so they are really long, and with the width you dont really need the length. but i could imagine the 189 would be really fun for jumps.
