So I switched from Rotos to DRs a number of years ago just because they last about twenty seven times longer, but recently I got the urge for that dear old roto sound. Now, has something changed? I opened a pack in a music store and there was no cloth wrapping? I'm not sure which 66s they were but they were 66s. The other part of my memory loss is this - is the only swing bass set of 45-65-85-105 nickel? The 45-65-80-105 is the steel one right?
