What would be a hard rubber version of Metalite M7? Thanks in advance.
This is it.I don't think there is anything quite like a Metalite. With that sharp dip right after the tip, they are completely devoid of any highs. Same goes for the Graftonites.
I farted around with many of these over the years (Metalites and Graftonites) because they are cheap, all 3 chamber sizes. It was kind of fun adjusting tip and side rails and DIY baffles for a while. I finally gave up and moved on.This is it.
The closest would be if you put your own step epoxy baffle in a mouthpiece that duplicates the dip after the tip rail.
