I've had the Taom on a Mezz Power Break + Pro R shaft for about a month, the newer version sourced from Mika. So far, I'm enjoying it very much, and have very little negative to say about it.
Prior to this, I ripped off the stock Mezz Sonic tip to try out an Outsville Solid break tip. I'm a fan of their Ki-tech soft and medium tips, but this Solid tip played extremely soft, feeling only slightly harder than a typical layered soft tip, and definitely not a satisfying amount of energy transfer into the ball.
The Taom doesn't feel too hard like phenolic. It has a sort of elasticity to it that feels like it's bouncing energy into the cue ball upon contact. I'd been using a BK2 before picking up the Mezz, and in a side by side comparison of the setups, I'm happier using the Taom + Mezz for ~80% power breaks, and the BK2 for breaks harder than that. My break style attempts to mimic Ko Pin Yi (who does use a BK2 it appears), and for this style, I'm quite pleased with the Taom. I wasn't so big on jumping with the BK2, I never felt comfortable jumping the distance that I could clear a full ball with using that shaft; perhaps the low deflection properties of the shaft don't make it as practical a jumper for my abilities than the much stiffer Mezz Pro R shaft. With the Taom on the Mezz, I can clear a full ball about a foot away with confidence.
Here's a video of a few breaks I recorded with the Taom-
