So I accidently ordered the wrong protank for my spinner since I didn't want dual coil which the pt3 is. Anyways I have a bunch of pt2 heads laying around and I put one in the pt3 since I like the glass tank and it seems to be performing nicely. I've only been using it for a couple hours but I'm scared it will leak. Anyone try this and it run smoothly ? I know that the new dual coil head don't fit in the previous versions but the old ones do fit in the pt3
