I buy and sell used chainsaws all the time and notice any more most of them have this so-called anti kickback chain and it may have it's place but compared to the "good chain" it just doesn't stack up. Maybe it's just me but I'd never buy it unless that's all I could get. I tried both kinds on a big maple a couple or three weeks ago and the homeowner chain acted like it needed sharpening even after just being sharpened. Anybody share my opinion?
