I like and have used them all (except the 145) but have used the 125 more than any other, I find it a very versatile weight.
Super strong, fly like a dream and if you put them where they belong they usually leave bloodtrails better than you'd expect for such a narrow head, (might be the rotation, who knows) but of course they gotta be sharp!
Finding Grizzlies at the moment won't be a walk in the park...they haven't shipped anything in months and a whole lot of places are wiped out on them. :(
I'm liking these new Zwickeys, they've got the cutting width of an El Grande but are single beveled on either side, so I can get left side now, and they are easier to sharpen IMO than the Griz to boot.
