I picked up a Break Pearl S70, from another lefty.
Looking at the flare rings, he tracks about 4" down from the fingers, and 3" down from the thumb.
I normally plug the fingers and re-slug the thumb on his used equipment.
He has started using equipment with the MB on the right side (track) of the thumb to smooth his equipment out on the backend.
I'm a higher tracker 1/4" from the thumb, 1 to 1-1/2 from the fingers.
Here's a picture of the layout....What will the reaction be for a higher tracker?
I can vary my speed, revs, tilt, etc., fairly well.
