Yes, agree, each cartridge will be different for vta.
Congrats, sounds like you've done well.
And yes, no need for finger lift. You'll get the hang of it eventually and develop your own lifting style. I try to emulate Firebaugh, and put the pinky of my right hand down on the table between the two pillars, and fold my other fingers on top of the pinky, and then lift the arm in the middle with my index. Works like a charm. I can now cue more accurately like that than with a cueing lever and fingerlift. I suppose like using a fork in a way, which i'm good at, too.
You'll see how easy it becomes with time. Some newbies take to it instantly, so don't be afraid. If you miscue, due to the damping, you can grab the arm before damage occurs. Enjoy!
