So, I'm back to playing my '95 Ibby ATK300 again. It's got some ratty EB Slinkys on it now that really NEED to be changed. I've switched to Flats on my Jazz and Flats and/or Half-Rounds on my Ps... so these days, tactile-y speaking, i'm more comfortable with flats. I haven't really been able to find anything discussing flats for an ATK specifically, but i HAVE seem some talk about flats on Stingrays... which is similar... and the consensus i've seen is that Chromes are a good fit. If anyone has any input, i'd love to hear it!
