I've skied both, but i have torn the fuck out of 175 arvs the psat 2 years. I was a previous pretty hard core racer so i definately rip them thorugh crud, groomers everyday as well as the park. The Guns don't hold up on groomers worth shit im sry to say, i don't know if its what there made of or what, but overall i think the arv is a way sturdier ski that can get its shit tossed everday in any condtion and still ride well. and u don't ski the smae ski as every 35-45yo that thinks there "hip" hahaha. Plus its buttery fun!
