I have a mod for the ST Pro designed and currently 3D printing, but need a ST owner to be the test pilot for me.......
Does anyone have a ST or getting one soon, I can email you photos and design drawings of the idea and we can go from there, BUT I ask to keep it quiet for the moment.
The mod is totally removable, no damage to your game and should be effective, sorry for teasing but want to get this right and then release them.....
Update: 11-10-13
the proto of the mod has been posted in my section and can be found here
