I purchase only CP air tools. I've worn out and/or broken several other brand 1/2" drive impacts until I ran across the CP 749. I have several of them and they last longer than any 1/2" drive I've had. I've also use the 772H when I was working in former shops, it's a good tool, and I was about to purchase one for my service truck when I spotted the CP 7769 and purchased one. I have to say I really like the 7769. It's lighter since it's a composite gun. It's also shorter than the 772H, gets in tighter spots. And it has greater reverse breakout at 1400 ft/lbs whereas the 772H is 1000 ft/lb breakout in reverse. But I really like the "lighter" part, it's much more friendly to muscle around than the 772H.
