I ended up getting the angled , comfort grip, spring, no notch, 8" model 71 22 200.
18ga, 15ga brads = no problem, easy snip , snip , snip.
Same for electric fence wire (not sure of gauge) and finish nail #4 and #8.
8d and 12d galvanized nails a little effort but easy cutting.
up to #10 machine screws no problem.
GRK R4 wood screws #6 easy, #8 some effort but no problem, #9 a two hander but cut it. #10 hard to cut in fact i used two hands and went from two directions and didn't get through.... decided not to push it any further to make the cut. Maybe the notch version would cut the #10 ?
Zero damage visible on cutting edges, no light showing through closed cutter edges.
I would definitely recommend the comfort grip models based on the amount of squeezing required to make some cuts. I have not tried the regular grip but I can tell that I am glad I went with the comfort grip. There is a 10" (250mm) version available but currently only in regular grip. The longer handles would be easier to get two hands on but I think not having the comfort grip would be a big offset to the better two handed use.
