well i haven't skied the pair i just bought, but my previous pair (had to sell to help pay for shoulder surgery) pretty much made me a 10x better switch rider overnight. and not that i'm any good at technical jibbing (i suck) but i can ollie them twice as high as my msp's and i can also pop off the tips (i wouldn't give myself enough credit to call it a nollie) with the same amount of force.
but dude seriously stop second guessing yourself, keep the lizzies and get another pair of charger skis, or trade them for something burlier, because they are too soft for an everyday ski for what the bird has to offer, and so are maidens IMO.
