Wow, I though I was the only one who used the second and third mouse buttons for movement
Do you use left-ctrl for strafing left, left-alt for strafing right, and shift for jumping? That's how I had it for a long time. It was really hard to convert, but I'm using the WASD config now and it feels a lot more natural, all movement is taken care by my left hand and my right hand is aiming and firing. I'm not saying you should change your config though, just sharing my thoughts

I still use my Wingman for FPS gaming, and my optical for other genres, and general use. This cuts down on the buildup in my Wingman and should help preserve its life for a longer period. Have you tried
Mouseskatez? It makes the Wingman even more smoove, real nice stuff. Good luck
