In reply to planetmarshall:
Surely it is completely rock-dependent?
10 draws is overkill for most grit. On a 40m+ pitch at Wyndcliff you would be running it out.
A load of cams is adequate for grit, but on limestone I'll carry anything and everything.
Totems in smaller sizes are baller on limestone but I don't know if you can beat the crunch of seating a single-axle Technical Friend on grit.
Micro-wires essential for a lot of limestone slabs and slate. Pointless on a lot of grit.
Need loads of alpine draws for 3D granite but not necessary on plumb cracks.
Some pitches in Avon, all you need is one draw to clip the lone rusty peg in the middle.
