I've got the 169s (range is +3 to -3) with rossi 120's. They're mounted at the +3 line.
Your toughest competitor lives in you head. Some days his name is fear. Or doubt. Or gravity. Stomp his ass
the more forward you mount it, the shorter you make your turning radius. this is neither good nor bad, as long as it is what you want, and you know how what you do affects how they ski. it won't make it 'ski shitty' as someone said or something like that, you may even prefer a forward mount for all-mountain, but just know that it does make a differance.
i didn't come here with pants, and i'm not leaving with pants
nah dude it moves you away from the actual center of flex. making the ski ski like its not intended too it might not matter if u ski park all day, but if u do other stuff then keep it within like 2 cms. maybe even less. or not at all.
