Yes, the STL-V2 will most definitely beat it in terms of throw. I can take some indoor beamshots of the 3T6 later tonight if you wish.
I have a thread here which compares the STL-V2 to the Crelant 7G5V2 and skyray king.
I also have a thread here comparing the STL-V2 to the TR-1200.
bottomline (throw): 7G5v2 > tr-1200 > 3t6
flood: 3t6 > 7G5v2 = tr-1200.
