i had chronics last year with the reactor...dope setup because since the chronic is stiffer its super stable and you dont feel sketch landing switch fast...the bindings broke and line sent me invaders...they are not nearly as durbale as the chrons and at high speeds you fell less stable...the chron was a 167 the invaders are171 and the chron felt less sketch when zipping...however if you ski only park go invader...all mtn or 50/50 go chrons
