Cannot go wrong with any of the center pivot designs IMO. The quietest, most shock free bows i've ever shot. I absolutely love the standard factory grips on the Bowtechs also. I'd say don't hesitate if the price is right!
I own the General and have shot the others and am considering a Sentinel sometime this year to use for 3D, but now that you mention it.....I may look for a used Commander myself and save some cash!
As far as Center Pivot designs go, I agree you can't go wrong. The Guardian is probably one of the best bows I've owned, and I almost regret selling it.
It's hard for me to say on the Commander becuase the one I have is a 50lb max draw that I bought for my wife and all I can compare it to is my 70lb models. Plus, I've only shot it a handful of times, I can tell you that pulling 50lb's is a lot smoother than pulling 70lbs.
I believe it does have a draw stop on it, which I like and is one of the only things I didn't like about my Guardian.
I'm sure it's just like my other BowTechs and is definitely a shooter.
Top notch bow. Can't say enough good things about it. Make sure he gets the 2008 cams though. There is a big difference between the 2008 & 2007 cams.
I've shot them for indoors and 3D, no complaints at all. Great grip, great brace height and plenty of speed for what I was trying to accomplish.
You can see from my signature that I also own an '08 Commander, in Testaross. Love the bow. Do not expect to ever get another. Sometimes wonder why they continued making other models after designing & making such a great bow.
If it's in good condition, tell your buddy to get it. I bought mine pre-owned in great condition in 2009 for $400. Haven't looked back since. If for some mysterious reason he doesn't like it, he won't have any trouble selling it. Buying this bow would be a no brainer.
