You didnt mention these but since I wanst sure if you looked at them...
They come in three sizes and three widths for each size
They go as narrow as 7.5inches (probably what I will get)
An optional "canyon cut" is also available, which I think is good if you are planning on falling down
Priced at 660
50 more for the canyon cut and 90 for your choice of powdercoat
