Now,  the way Buzzard described doing rolls on SJ's,  I use to do the same thing as well,  Call it a Power Roll.  Not using a setup wake to get your lift but using the offset momentum of the ski to hit the water and then literally bounce it round into a roll.   But not describe it in a condescending tone.  You can get hurt doing anything.  How you think I got my nickname.  Was going for a huge nose stab and came out of the footholds.  ski went inverted,  pole extended down,   I split the pole with my legs.   Nuts got all swollen up,  drank alot of beer that night, afterwards I said "Call me Big Kahuna"..........     Someone said,  "You mean Cajones"............... I said,  maybe, but I like Big Kahuna..........  Name stuck.
