Thanks, I do have the 6061 and it’s my most played of anything I have. The boosted version has a quicker feel, doesn’t have the slight hang time/float of the 6061. Faster playing overall and feels lighter during play, easier to go horizontal. Still same general feel but has a more overall desire for aggressive play. Even with the flat bearing it’s very stable. Just put an NSK concave in so things should get even better.
