i like my snowskates to have lots of concave, twintipped, stiff with very large nose/tail as i like to do ollies and various fliptricks.
The snowskate shouldnt really be too long, but atleast longer than 35 inces. And having sharper edges make you bite the dust when doing boardslides (especially if you allready got the turnaround style on fs boardslide from skateboarding). Btw, how high do you guys ollie? I ollie about 18 inces of the ground
which makes it fun to ollie up and slide on things. 2 years ago i slided a 6 meter long, 50 cm high ledge.
