Personally, I've only used Reeves, but other guys do great work as well. Aligning the valves so that air flows correctly through the ports is just helping the horn work the way it was supposed to work. Some really excellent horns are known for alignment issues. Take Schilke for example, they have used felt pads forever. When the horn is new, those pads are fresh. In time, they will compress a bit. At one point or another, the horn is not well aligned. I have some great Schilkes (P5-4, E3L, G1L), so I'm certainly not knocking them. I just think alignments are a good thing - even on high end horns.
