I’m not! LOL! I think the TF’s will surpass the PM’s.
I have both heads.
The PM’s are nice and even better so for there price. If more power and cam lift are desired, the TF head is it for a readily available head today. How well or much one takes advantage of the head is another story.
I have not seen, read, or heard of anyone maxing out (or really putting the screws to them) on a set of ether.
