Kreyzhorse & Smokin250,
Thanks for your insights. Fortunately, I have a little gift money, so I'm going to splurge on the Harris bipod. I'll go with your recommended 13.5 to 23, and will also get the swivel feature that so many have appreciated (allowing for uneven surfaces, and leveling the rifle/scope).
I hope it works out for you. I know its one of the best purchases I've ever made.
