Linear tracking turntables, whatever happened?

Whart -  My understanding is that both weights work in concert. One does the locking ? Does Frank offer smaller weights to get you to the end of the rod with that cart ?  

uberwaltz - I was just thinking about that this morning. lol
From our ET2 Owner perspective you are very lucky. 
Worth the drive. .   

Maybe indeed.
I did see they were selling the et2.5 for $4500 🇺🇸 💵.

Sorry.....

@ct0517 - I can ask Franc about the counterweight. Dunno. This is a pretty old arm, circa 2006-7 is when I bought it from an  authorized dealer. 

@whart 
I doubt the arm design has changed. See what Franc says. Myself, I would be tempted to remove your counterweight and bring into a machinist. He can make up new counterweights for you using the thread pattern the rod uses and in whatever material you like to match your arm. i can't see the cost been alot and the reason I mention it. You could start by having him make something that will work. Then if the difference is dramatic, have counterweights made in the material you prefer.   

From the looks and angle of the picture it looks you are giving up 15 -20 % leverage (physics)
If its a cartridge you are going to keep on there for the long term its worth pursuing. With vinyl rigs I have always found that it is the attention to the small details that make big differences.
