I just slapped my new Tenryu 12T on the TS55 today, and ripped for the first time in a piece of pond dry doug fir and HOLY CRAP what a difference!
They're available in various places, you're looking for the Tenryu PSW-16012CBD2.
Put the 28T Universal Festool blade to shame speed-wise, and I think it is the (cost friendly) solution to actually being able to make rips with a TS55.
What I can't speak to yet is longevity, time will tell...
