Which arv were you trying? The candide isnt a bad park ski to start on and it could also be a decent all mountain ski since the 2.0 is 102 underfoot. If you want just a good park ski to learn on maybe go with the 1.0 or the arv 86 and maybe 96, width will help them be stable and help double as all mtn skis but in park when you're learning the basics a narrower ski is gonna help you maneuver swaps, spin faster etc. Performance wise the flex of both skis is similar, the candides tend to wash out on backseat landings while the arvs can put them down, the arvs have a little but the 2.0s have early tip rise so both are probably prone to chatter in the tips on hard packed snow at high speed.
That's all I got, both skis have potential for quick damage but as a beginner it should take longer to break them, factions warranty works for park damage I think, armadas doesnt.
