I've been buying the Champions for a while and I can tell you I'm not impressed. The only reason I keep buying them is because I like the height of the 29 1/2" champion, I'm not a tall guy but I've been blessed with a long torso and the 291/2" is perfect. I'm knowingly throwing my money away on them to get what I want. I think I'm on my 4th or 5th Champion, broken springs, parts falling off, bent legs, etc. 3 weeks ago the left leg snapped completely off my last one.
I know a "guy" so I buy them at wholesale prices and I'm not throwing away 60 dollars every time but for what I've spent on them the Harris would have been paid for.
If the extra couple inches isn't critical to you buy the Harris, the quality of the 2 is not even close. FWIW the Caldwell may very well be a better "budget" bipod than the Champion.
