i have 3 avery jenkins destroyers. a 175, a 172, and a 167. to test them all. the 172 and 175 fly wickedly overstable. i really have to put every amount of torque i can come up w/ in my body to put them 550 bh, and i actually have to throw it hard to get 500 fh out of it. but the 167 flies alot like a echo or max weight normal star. flies really nice but really stable for the weight. got aces on all three alrdy in 4 weeks of having them. so im sold on them.
