I haven’t test driven a Calvin Elite enough yet to decide, but a few guys I know through PRS type Competition shoot them and love them. Alternatively, one nationally ranked competitor I know had one for 3 days and bailed on it - he shoots Triggertech Diamonds.
I’m a big fan of the HVR, and a big fan of the Diamond. I’m shooting a match with a guy next weekend, supposed to be squadded together, planning to test drive his CE. I’ll let you know what I think after having some time shooting it. I know it needs to be epic strides nicer feeling than the Timney 510 for me to buy one.
