Had the TA1 for a bit and have been spending time with my ta3. I have tried both on a few different simrell setups and will say it works but not ideal. Full titanium mvs, it gets a bit warm and isnt great for back to back its because of this. I have a blackwood stem with no airports that is awesome but the metal mouthpiece gets way to hot. I have used orings and filled it up with sic pearls, that works better but then the body gets pretty hot. I actually was using it on a micro setup with sic pearls inside and it worked but my finger would get a bit to hot trying to cover the airport. I have a dovetails on the way.
I have now tried it with boro, sic, and rubies. I would say sic is better for wpa as it really can hold and dump heat fast. Rubies have been working out pretty well with the stem setup. They seem to take a bit more to heat up and are slower to release. Id like to try zirc at some point but Ill probably stick with rubies in the ta3 for now.
