In reply to Brian Tilly: Neutrinos are good kit. Have a couple in my rack and was climbing on a friends set of neutrino draws in Spain this month. No concerns about using them whatsoever.
However, I prefer DMM Prowires. Same weight 36gms and strength is marginally better 24/8/8kN vs 24/7/8kN for the neutrino.
They are slightly different shapes and of the two I find the prowire just a bit better ergonomically. The neutrino is a pretty standard offset-D shape, the prowire is slightly longer with a more pronounced taper.
Got 80+ prowires in my rack, so that should hopefully tell you something (other than the fact I have too much gear).
