Interesting comments on the Terminator linear tracking arm from Dgarretson on the MM thread who has fabricated a lightweight carriage from carbon finer instead of aluminium....

The wand has dual front and rear counterweights for continuously adjustable vertical effective mass.
Total horizontal mass of arm, cradle, and carbon fiber sled is 45gm, and can be increased by weighting the air sled.

I've tried it with as little as 35gm horizontal mass and as much as 100gm-- approximating the range of horizontal effective mass from ET to Kuzma airline. So far less horizontal mass sounds better in all instances. This does not hold true for vertical mass.
Interesting comments from DG as they relate to the Terminator arm. I have only seen pictures of it.
imo - it is not valid comparing the ET2, 2.5 and Kuzma Airline in this manner because although the later Kuzma resembles the ET2 in appearance their design objectives are as different as apples and oranges. This has been discussed here.
Some facts
The Kuzma Airline requires the wires and air tube for damping of the cantilever.
Through private Kuzma owner emails I have learned the Kuzma has difficulty with lower VTF and higher compliant cartridges.
Requires a heavier cartridge with a stiff cantilever. Any Airline owners disagree with this comment? I don't own it and the reason I ask.
The ET2 (2.5) in contrast can play a light high compliant (how about a sonus blue gold at .2gm) or an Acutex 4 series then turn around and play a stiff cantilever on a heavy MC.
The ET2, 2.5 requires neither the tubing or wiring for damping and tracks best with no wiring.
I know this because I use it this way (no wiring) now to level it and have had it track the record this way - once.
I say once because I haven't figured out how to get any sound when I run it this way.
again I ask - how do we make it wireless ?
Johnathan Carr, Peter Ledermann or another cartridge designer if you see this - this thread is at over 150,000 views.
Does anyone have any plans for a wireless cartridge ?
I will buy your beta cartridge even if it means putting in some kind of computer chip in my preamp.
C'mon Nobody likes wires anyway. They just get in the way.
Unless you can set the wires up like Frogman.

I have no problem with that.
Remember when phones needed wires. My kids don't - they laugh when I tell them.
The ET2 also has VTA on the fly that doesn't change parameters like VTF.
Set your Airline at the highest and lowest setting and you'll notice your VTF has been altered.
This is an owner confirmed comment.
Does "any" other arm exist that does vta on the fly?
Same thickness records have included cut angles that are random from the different record plants.
How do you guys deal with this?
The ET2 can also be tuned for different compliance cartridges MC and MM.
