Personally I use just my index fingers to alternate between these but I’m realizing how inefficient this seems when I look at the controller scheme. Seems more like it would be more beneficial to use middle and index fingers but I don’t think I’ve ever seen anyone use that? But maybe some people do? Was curious if any others out there did or knew of others who do.

Just Index fingers. I use middle fingers for back buttons if the controller has them.

Index fingers unless I need to use the bumper buttons at he same time.

I alternate between using my indexes for both the bumpers and the triggers, and using indexes for bumpers and middles for the triggers. Depends on how i’m feeling

This is for my steamdeck which has a similar setup. I find it is game dependent. If I don’t have to use them in tandem I tend to just use the index and move it back and forth. Some content I have to use it a bit in tandem like in cyberpunk if you are in car combat acceleration is right trigger and fire weapon is right bumper. In that case I use the index and middle. It does not happen to often so I do have to get my mind setup for playing that way while in the content.

I used to be an index fingers only guy, until Returnal. You really need fingers directly on like 5 actions at all times to keep up with the action sometimes. So now I use index and middle when the game calls for it.
