Basss brings up a good point about my MicroRack(tm) project - maybe a rack bag would be a better bet. MF carries Warwick's RockBag in a 12" depth, but has no technical info. I can't find anything on Warwick's site, either. They also carry Odyssey rack bags - including a five space model with 11 3/4" behind the rail, which depth would work a lot better for my project than the XRack: http://www.odysseygear.com/products/b_rackbags.html Odyssey has a slide-out carpeted plywood rack that fits in the padded nylon bag - it seems as if it would provide a lot of protection for the gear. The penalty is weight... Also, a 5u Odyssey bag would allow me to add a power conditioner to the rack. Has anyone seen or used either product? Comments?
