the cherry kiwi is capped construction and stiffer than the BL,
the Blueberry is very soft compared to skis like the ace of spades and the suspect. Much better flex points IMO, still really stable underfoot, i have two pairs, the bullets(old Blueberry) and a new pair of Blueberrys. Im only 145 lbs so i love the flex of those skis, really easy to manipulate
