Hi Laurie,Flex-Pod - it still amazes me how many people simply won't try it as they dislike the idea of a 'bendy' device. This should definitely be considered by those who grew up with the Harris and similar and like to 'load the bipod'. For those who prefer models that slide / track on the ground (and they're the norm in the UK as we mostly shoot off grass turf), Tier-One Carbon, The Shooting Shed's 'Stotteben IV', Dolphin Gun Co. 'AB Bipod', and Joy-Pod are all excellent. The Tier-One Carbon and Stotteben are really wide (2/3 metre between the feet at low settings and the 'AB' is only just shy of this width) and very stable - I now use bipods nearly all the time in F-Open instead of a front-rest.

In GB F-Class Association league rounds and among top club FTR shooters we see more Joy-Pods in use than any other single model, but Stottebens, T-1 all-metal and Carbon models, Mystic MPods, Dolphins are scattered around the field. With my retirement from top-level FTR, probably only the FLEX-Pod won't appear.
Apart the 25 gr. weight difference, which are the main differences between the Dolphin AB Bipod and the long legs Tracker?
