These slopers work well on a 40 degree. Great texture which is skin friendly. Enjoyable because there is no incut or grooves tempting you to "cheat" the sloper. Yet you can orientate them to behave more like pinches with thumb catches. Had purchased these to consider the XL's, which are double in width taking up more woody space. The only wish is for an in-between option. I like the width and height on these, but having them with a deeper hold depth would be ideal.
