Personally, I really don't care how MH uses his 11.5" Doinker. That's his business and I don't wanna know about it.
Seriously, I had an 11" carbon rod stabilizer for hunting several years ago and I did not like it. I do use a longer stabilizer in the 11"-12" range for 3d, but for hunting I like to keep them 7" and under. The reason for this is I found that I was bumping things in my stand with the longer stabilizer.
For the distances I will shoot for hunting I can hold steady enough to smash the 10 ring on the deer, so it hasn't been a problem.
