Whoa, either these are hard! My wall is 20 degrees overhanging. I have the "Small Simple Crimps" sets #1, #2, and #3, and I can do 12-ish move endurance routes on those sets. I'm not super strong and crimps are not my strong suit! So these may work better for you! I boulder V6-V8 at the gym and V3-V4 at my oldschool crag. I can do 1-arm bodyweight hangs on a 2cm edge. I bought these thinking they'd be ~V3, but I only do maybe one hard more on these. They've got very little bite so they are desperately, desperately insecure. There's no way I can link multiple of these together into a single boulder problem. I can't even tell you how hard such a route would be, because these are way too hard for me.
I'd recommend these for moderate overhangs if you're a freaking monster.
Texture is excellent and they're well made. They're not identical, but they're not easy to tell apart either, so you get less diversity than you get with some of the other sets. These feel like good holds to get in a mix of colors in order to add killer-desperate moves to your other sets and problems. I really don't recommend getting these all in one color (like I did) unless you want to make some really desperate boulder problems.
