I bought the naturals set and was very excited having had some metolius holds in the past.
Sadly though, these are very poor quality. All but 2 of the holds have the opening/channel for the bolt misaligned. The bolt actually goes through at an angle, not 90 degrees to the base, which means you can't fix them to the wall well enough to climb on thrm.
I'd also not class these as roof jugs myself but perhaps I'm just not strong enough. Excellent for heavily overhanging walls and doable on a roof circuit but only for advanced climbers I'd say.
