I think the whole set-up for the zoomatic snares is another wonderfully goofy, typically slingerland concept. THe snares are extended on the throw-off side, but not on the butt side!?!? If I was using replacement snares, I'd just use normal ones with string on both sides, and skip the whole metal strip dealio...That being said, I think these snares sound better with the original Slingerland snares, than they do with the Puresounds...
Hmm, While I haven't sampled these particular Puresounds on any of my Slingy Snares (5x14 Krupa Sound King, 6-1/2x14 Spitfire, 5x14 TDR), I did once buy a set for a mint '60 COB Supra I once owned (#1614), and in truth personally preferred the original '60's Wires better than the Puresounds. I noticed a much darker tone with the Puresopunds on this particular drum, it killed the wonderful 'Morello-like" tone, and crack, and they came of 10 minutes later.
I didn't dump those #1614's though, and hung onto them. Later acquiring a mint '75 Supra 6-1/2"x14" LM-402, thought I'd give them a whirl on this Drum, as something seemed missing, and there was a very nice improvement over the stock Wires. And there they have stayed ever since, as the Drum I finally felt sounded the way it was supposed to sound, deep, wet, and lucious (Ala John Bonham). I did note a difference in build between the stock Luddy '60's Wire versus the Luddy '70's Wires, and perhaps this was one of the reasons? ('70's wires looked to be of much cheaper build quality)
Also again with a mint, once owned '70's Big R Dyna, the Dyna re-issue Puresounds were an improvement over some "morphodite" wires the previous owner rigged on the Drum, until I was able to acquire and sample a set of NOS Dyna Wires I picked up. Again, in this case, the stock NOS Dyna Wires sounded better than the Dyna Puresounds IMO.
I reckon everybody's mileage will vary, with personal tastes, and the particular snare drum. Mark
