Mods for a ProFly?

What are some mods for a ProFly? Like to give it a bearing and different response and what not. Any advice or help?

Thanks

Silicone recess?

Oh! I popped the caps out. lol :stuck_out_tongue:

I got a guy on the Nation whos gonna mod it for a bearing and recess it for me. And he might even toss my DM Rings on it.
