I'm in this Camp. But I Don't Know Nothin 'bout bearing edges (too much unkess they are damaged). I would add in my limited experience - Tuning Snares is an elusive Art to me. My OCD (Limited , Thank God) forces me to attain the "sound of Perfection" form the few Snares I have. Trying a number of different batter heads, tweaking and re-tweaking the head, re-adjusting wires, and fooling with the Reso head too, in my mission to get "That Sound". I've been influenced by watching too many You Tube videos about the this subject - now realizing how many use Miking that influences those sounds. I don't Mike up my drums - as simply playing at home in retirement as a "Hobby". I did stumble upon an excellent channel from Rick Dior! When I posted comments on a video by him unrelated to snare tuning, but expressing How Much I liked the Snare sound he had he returned a Link to his Drum Tuning videos - very thorough and informative. He didn't Mike his drums in the videos from what I could tell.
