I don't think new ones would be any different..? Something is off with the cooldown calibration..
Initial heat up from cold first click/second click is tuned pretty good for a decent go of 3-5 nice (not roasty) hits assuming you stop right at 2nd loudest click. Then when placed on the Reload magnet 1st (light) cooldown click happens around 2 minutes after.. 2nd louder cooldown click is about 5 minutes after (if you respected the 2nd click exactly) these times are longer if you overheated the Tempest to push it (roasty) first go from cold. If you want to reheat right after the first nice 4 or 5 hits.. use the visual indicator and bring it to about the 2nd mark then hit.
Hopefully he comes out with some updated clickers.. It's my only gripe with the tempest but the indicator is a good workaround for second go in the meantime.
