I tried this setup recently in my 6.1 95 at I think 56# mains, 52# crosses.
After about 5 or 6 outings with this setup, I'm now down to reading 43# on raquettune (from 53#) and have found the stringbed has started to buzz as though something isn't right.
Not sure if this is normal but it feels odd.
Hitting with it sounds like an APD now.
Should I cut out the crosses? Cut out the whole thing?
Could it be a grommet? I can't see anything weird about them.
