I always thought the Luxe 2.0 shot the smoothest and quietest of any spool I've shot. But then again i have never shot a DM 14
I also really like how the Bob Long Victory shot smooth (in-line poppet) I owned one for a while and really enjoyed playing with it.
The LV1 is a super smooth shooting stacked tube poppet. The G6R is another smooth shooter.
Out of all i really like the Luxe. Smooth, quiet, great packaging, and great trigger.
