most importantly from reading your own system description, the woodsong catapulted your energy and enthusiasm to remake your entire system - i so hope you don’t lose that ;-)))
i have a Triplaner also. While it’s a wonderful arm, i am in line w Thom at Galiber Design as he develops his hard counterweight mod. The current system is lossy. Finally, J Carr noted adding a ceramic spacer or other mass to Triplaner and shrink sleeving the finger lift can improve sonics. Some Triplaner users also report improvement by removing the damping well. I run a massive Kuzma CAR-40 on mine, it sings…. My absolute best to you !
