I have two Larue Harris BRM-S LT706 bipods. Not an add on Larue mount. The factory Larue 706 is not a mount on a mount, but has the mount integrated to be lower profile and lighter weight. It also uses a tension wheel for tension adjustment.
The Larue throw lever works great for one rifle. It works well if you have a picatinny rail that is almost EXACTLY the same dimensions as the first. In reality, picatinny rails vary and a single bipod was too loose on some rails and too tight on others. Using the Larue wrench to adjust tensions on the bipod is a pain in the ass and time consuming if done several times in one range session. If the lever is too tight it is a real pain to remove due to how close the lever is to tbe bipod because of the low profile design an inability to get more than a finger tip on the lever.
By using two Larue bipods... one set up for tight rails and the other set up for loose rails, I always get a bipod that has a lever that closes and does not rock, although some rails are little tight or on the verge of loose still (mostly just polymer picatinny rails). The Larue is the most stabilized bipod IMO and tbe Larue version is MUCH lighter than an add on mount and long tension lever added to the regular Harris.
I prefer the Harris because it can be locked down solid for shooting groups and the single mount Larue is the most rigid mount when tension is correct.
Would a Badger Ordinance picatinny be a better choice if I had it to do all over? One thumb screw bipod can do all picatinny rails but I would be more apt to get one that could also do ARCA rails. Though ARCA has issues with no recoil lug and great tension being needed.
ARCA rails were not a thing when I went Larue LT-706 the first time and add on ARCA rails to existing AR15 FFrails (Keymod and MLOK) were a total failure for me, as they had too much deflection in shorter length ARCA plates used on a tripod. The actual rails deflected, distorted, and bent when I used a RRS ARCA throw lever mount in combination with the ARCA plates that only distributed force across two or three bolts.
If you have full built in chassis ARCA rails on bolt guns and picatinny rails on other guns, a dual ARCA/Picatinny bipod adapter is better from a utility perspective, if you don't need a super fast QD function and can torque down the thumb screw with a tool and don't mind needing a tool to remove. I just don't trust hand torqued screws to not come loose and ARCA with no recoil lug will slowly shift if using finger tightened screws.
Sorry for the long ramble but some experiences for you to consider.
