Bi-pod recommendations?

[YodaVader]

I have a Remington 700P and am looking to buy my first bi-pod ever. Mostly the rifle will be shot from the bench. I thought the Harris might be a good choice. They list a 6"-9" height and a 9" -13" for the 2 versions I am looking at. Also a swivel base and a solid base. My thinking is , unless you are shooting from a perfectly level surface , the swivel base would be the way to go. Which height range would be the better choice for bench use?

Any experience with the ones I mentioned or any other recommendations are appreciated.

I like the 6-9" swivel version for bench shooting. It also will work for prone, though it might be a bit low for some. The swivel is nice, and can be adjusted to give a loose or firm position.

Ditto. 6-9 swivel with leg notches for me. (S-BRM)

I use the S-BRM with a Podloc. I think the Podloc is a necessity with the S series Harris Bipods.
