Prometheus Double Torque Gear Full Set for Ver.2 Gearbox
 

Has anyone have experience with Prometheus double Torque Gear Full Set for Ver.2 Gearbox ? Im looking for upgrading my Gr25 to 450 fps and I need to reinforce a few things that are included in that kit. If you have any experience with these gears, how the battery drainage? Rof? Im looking to couple that with the prometheus MS135. Let me know.
Thx guys.

I use it. They seem to work really well and I have had zero issues with mine at all. If you're using a sub-c (large) battery pack, then you won't notice much of a drop in ROF if any.

whats your set up? Fps, spring type? Im want as much realibilty as possible and I wanna make sure that the parts are compatible
