i've been skiing dynastar nothin but troubles the last 2 years cause i wanted some beater skis to learn park on. but im for sure buying good skis next year since i've progessed so much this year. the only thing i have a question about is that my skis are labeled as partial twin tips....im obviously going to buy full twin tips but how big of a difference is there? i have some trouble riding 5s out switch or just getting going fast backwards in general. is this partial twin tip thing bringing me down or do i just need improvement?
