Guys-
The newer solos are a far cry from the old ones, just as the new mechanicals are. If you are happy with them and they work for you, by all means enjoy them! <img src=icon_smile_wink.gif border=0 align=middle> As stated, on thin-skinned game, not a problem for most who take the time to correctly tune.
Take one of your steelheads and throw it through any tightly-stretched hide. (I happened to have a sheephide kicking around when I did my testing last spring) I made a 2x4 frame, and stretched the hide over it, then stuck 2lb ethafoam behind it to determine the best penetration. There ain't a mechanical on the market that will stay with with a fixed-blade on this type of test, and when you add a 1/2" piece of plywood behind the hide to resemble a rib hit it gets even more distant. I will say in all honesty the steelhead 100 is the best mechanical out there currently IMO and offers the best penetration of the mechanicals, but it still does not stand up to the abuse or have the penetration of a fixed in real-life instances.
Of course, in most instances, both will penetrate fine on the 17" or so chest cavity of a whitetail. No arguement there, but again, WHY take a chance, any chance at all? Just my own thoughts, Pinwheel 12
