Bob, looks like you have sufficient response to make your decision. But I'll add a little reinforcement.
Years ago I owned an original (square motor) WTTT and arm. It played music but was responsive to improvements such as the new black platter, a clamp on the fluid cup, and damping on the arm tower. Still, as Lew suggests, the WT arm was always in question. For one example I could never get the same tracking force measurement two attempts in a row. What kind of precision does that suggest?
I replaced mine with a Kuzma Stabi/Stogi Reference table and arm. This was a significant upgrade offering extended bass, increased overall dynamics, and much better decay, most noticeable on piano. More recently I've listened to an SP-10 Mk2 and even with a (temporary) compromised plinth, it shows potential for bettering the Kuzma.
The step from a WTTT to a Technics should be a no-brainer.
