I love the middle one wow. How much are these?? Thanks for sharing, here is my input of setting up a custom profile for MW. I tend to use paddles more than buttons as it's quicker and more effective in my opinion. Also I do a lot of weapons changing, sliding along the ground, throwing lethals and non-lethals. These are my main settings:
I make the upper right paddle the right bumper and the other one left bumper for the simple fact you have to move your finger to get to your lethals and non-lethals, and this way I can do it better. Once I've done these 2, I usually set one of the bottoms ones (the left one for example) to crouch as when you set it up for B, it becomes much quicker for me to execute the action. The other bottom paddle I normally set for Y, so you can change weapons a little bit quicker.
All other settings are completely up to you, but these ones literally make my life a lot easier and don't let me die fast. I hope someone will find it useful ?
