Thanks. Clearly well crafted, depth of edge seems fairly generous though.
the megarails hold sizes are...
Four Finger Edges - 20mm deep
Two Finger Pockets - 32mm & 25mm
Mono Pockets - 30mm & 20mm
... obviously depending how strong you are is the line in the sand, but personally I wouldnt put the megarails in the generous category. The monos and small 2 finger pockets take some hanging on to. 20mm is about the size of a standard small campus rung, if you were needing a comparison of how that depth would feel.
