looking for any upgraded top mount for sale (thumb)
How much are each of you guys letting these go for...?
There probably really isn't any HP gain between sizes. The thicker one probably doesn't heatsoak as much as the thinner on. As for the SU TMIC, it looks like it's 3.25 but that's what I think.Is there a difference in HP gains between 3.25 and 3.5? Also does anyone know the core size of the SU TMIC?
