Mods: - Gutted rumble pack. Yes you heard that right. Vibration is completely unnecessary, it only throws your shot off (experimenting done via CoD Warzone). Without the rumble pack, it cuts down the weight significantly, thus reducing wrist and hand fatigue. You'll notice an immediate difference.
Far better than the default black and grey. This is key--pressing down the stick shouldn't be a chore, and the hard material used can make your thumbs go nuts--again, it will throw your shot off.
I added wider, slightly softer silicone grips that add more friction. One cool feature from the Elite Controllers is the ability to fully customize response curve and hair triggers. The problem is that Microsoft gives you no indication of what works best and leaves you to experimenting on your own. Fortunately, I've already figured that part for you and pre-loaded the controller with what I believe is the ideal FPS settings in slot two. Slot one is still default.
The elite controller design is nothing to write home about. I did something about that, as you can see.
