Is there any performance difference between the T3 and T3s? I know about the bases and it's cheaper to change out just the coil rather than the entire base, but I want to know if the draw is any different. I have a T3, and I'm not too happy with the draw (too weak/airy). I just hate to give up on it, so I considered buying a T3s base and a coil to go with it. Will this make any difference? Or should I just let it go?
