Sounds like on the support hand side, so 9 o'clock position if right handed.
I have a X300 on the 3 o'clock position. Kind of ass backwards, but because I copied a picture of a military M4 setup. With a little LARPing around my house, the switch position works pretty good. Operate the light paddle switch with the index finger and laser with the thumb. Same for shooting on non-dominate side.
Looks like a solid setup.
I know at least two well respected shooters (at least I very much respect them) have the same setup on at least one of their guns. My preferred is the X300 at 12 o'clock in front of a fixed front sight. No laser for me. . .
A least on any gun currently. . .
For your particular setup, I think I would have it the same way.
For the gun with Surefire G2 on Haley Thorntail, I have the light at 10:30 position. It's slightly out in front of my support hand when shooting, but I can easily hit the tailcap button from either side.
For the gun with the Surefire M600 and pressure switch, the light is at 1:30 position. I have the tailcap with the activator button along with the pressure pad. I tried putting the light at 10:30 first, but the cable coming out of the tail cap messed with my support hand when shooting righty (dominant side). I think I could push the light out further to mitigate that, but I wanted to keep the light a little further back for now. I have the pressure switch with the Cloud Defensive LCS, which does a good job of securing the switch and routing/securing the cables, but it also raises the pressure switch a little. Just enough that I can see my hand ever so slightly through the LPVO. It doesn't obscure the reticle at all and I don't think it will bother me, but I did notice it when LARPing. I'll have to shoot with this setup and see. When I shot the LPVO setup in a carbine class, it was without the light and pressure switch.
