Replying to I need help with ski sizing.

I am 5'4" (Still growing) and for the last two years or so i have been on 151 line invaders and i am ready to get new skis. i am trying to decide on whether i should jump 10cm up to a 161 or 20cm up to a 171 ON3P jmo.

My concern with the 161 is that it is not going to be the right size for very long and that i am going to continue to have trouble with landing consistancy.

But my concern with the 171 is that it will be too long and that even with the rockered tip i will still have trouble in the air with spins control ect.

any help/suggestions would be much appreciated.
