Folks, I'm very confused. I want to go "old school classic" on my new AVRI, which means flats, but I am at a loss to know which of the many brands to choose from. On my other basses I have been using Hi-Beams (105s) and like the tension a lot, but it takes me months to get the strings our of "piano wire" mode and start to sound with some greasy, groovy thump. I tried Chromes but the tension was too high (that, and the string spacing on the AVRI neck radius is significantly higher than my other P's thus making it even more difficult to play!) I put a set of R Cocco's on but they make me sound a ringy and, well, yuck. Anyone have an experience with flats on an AVRI that sound thumpy and doesn't require Hulk Hands to manipulate? Thanks in advance.
