i suppose. from all the times ive been to bear they didnt really have anything that you could "progress" on. they had a long flat bar but not an equally long flat box to practice tricks. you guys are riding there all season so i cant say what you guys want. but you guys already have an s-rail. youre just adding to the circus. that s-rail is awesome though, i liked it. simplicity is usually the best way to go. it is nice to have features like an s-box or that u-box etc, but not out on the hill everyday. for everyday riding it should be varying sizes of flat boxes, flat rails in different widths and lengths, some mellow kinks etc.
like, ive never seen a long flat box there. maybe cause i never rode there enough but all the boxes there were short, that i saw.
