9 to 13 is what I normally use when groundhog hunting. It's low enough I can use it off a bench, but high enough I can see over some beans when they get a bit high. But, I also carry some folding cross sticks in case I have to shoot from a sitting position. It's not as steady as a high Harris, which is what I would use if I had to shoot longer ranged shots while sitting, but it's light and cheap, since I made them myself from carbon glass arrow shafting and some hydraulic fluid tubing, shock corded together segments.
I think I had mine made before Stoney Point's version came on the market. LOL
