I have not found a need for a triple-pull Ckyepod in PRS. In fact, I'd estimate that less than 20% of shots are taken from a bipod in PRS. You'll mostly be using a front support bag off of barricades, and flirting with when to use rear tripod.
For PRS, I have been very happy with the Atlas CAL and SuperCAL. I know some very good competitors that prefer bipods like the Harris and TBAC that allow fast deployment and stowage of the legs.
The Ckye single-pull standard and "short" PRS versions will definitely do what you need for PRS, and lots of very good competitors use them.
