I have Azzpadz and love them I mainly wear them. I also bought skeletools and doubled the pads as mentioned. That works great depending on what trick or terrain I plan to ride. What I prefer with the Azzpadz is I can more easily remove them at any time during the day. Skeletools you can only remove the padding easily since they are an elastic type shorts you wear.
Just my experience having 2 brands in my gear arsenal.
