Yeah, I'm not a big fan of my CO2s after putting them back on my board. The straps are very uncomfortable after a couple hours. I've never tried the C60 but would love to if someone gave me a pair. I'll just have to look out for a burton demo one of these days.
Don't go where the road leads, rather go where this is no road and make a trail.
I had C02's on my Never Summer Heritage last year, and then towards the end of last year upgraded to the C60's. The C60's are a bit stiffer, and are INCREDIBLY light.
I ride a lot of park, more than just cruisin and they suit me ok. I do plan, however, to try something more forgiving. I went all the way, so I can get a better feel for both ends of the spectrum, to better suit my own needs, in my own style. Granted theyre expensive but, well worth it IMO.
Just make sure you flip down your hi-backs when gettin on the lift! Burton does NOT cover it!
