In reply to Francois R:
For sizes 9, 10, 11, BD wired hexes are hard to beat. Rack really clean, the weight of big hex is sufficient to make wire cable flop, additional reach in some cases, lighet than original camp ones. Smaller sizes less effective on wire, better on cord.
WC Rockcentrics, hate them! Keep flipping over onto smaller rotation, much harder to seat than original straight sided variants.
DMM Torqnuts are ok, extendable sling can be helpfull/pain in arse to retract them to original length. This is magnified in winter when tape frozen, really not worth the hastle!! Second best after.
