Quality of surface blank ski???

You get what you pay for in the ski industry. Hope you aren't hard on skis.

It's like the line afterbang. Except you can draw on it.

Problem , im dont treat them very good special with the rails ..... Still worth to buy????

its hard to say, ive had multiple surface skis, and the quality hasn't been anything impressive, i snapped a pair, one pair delammed super bad and the base quality kinda blows. i had a pair of joystick these (which i believe are made by surface) and those actually held up amazingly well. ended up getting rockered slightly after a year and a half. but ended up with one edge crack on one ski and 2 on another after like 70 days of park use.

I have been skiing with multiple ski brands and after 70 days of skiing , there is no ski from k2 and armada , line and others that hold without cracking edges and that stuff

i dont know what skis you're buying from them but I had the domains for 2 years (roughly 150ish days in the park and tree skiing) and never had edge pullouts. the edges had very small cracks but they never came out of the ski.
