“As advertised these are big and hollow and very roof-friendly. My kids totally love these on every wall angle.
However, although they make one-handed moves on the roof a breeze, I noticed the holds flexing under pressure (not sure how much flex is required to cause failure), so Id rate them a little delicate for my taste. Use of the stabilising screws improved this somewhat, but since I weigh only 0kgs I probably wouldnt recommend as roof placement for heavier climbers. ,”
