I've had the SKS Raceblade Pro XL's for several years and really like them. They just fit over my 35mm Paselas - I run them a tad high off the tire. They go on in literally one minute and are 90% as effective as my full fender Zefals. For touring racks, we like Axiom streamliners and they go on and off in a couple minutes (4 bolts). We've used them off road quite a bit, plenty of rough gravel with Ortlieb rollers. Good foot clearance too.
