You’re right. Sync on hybrid seems to stiffen things up. I haven’t try hybrid Zero/Sync yet but I just tried hybrid Head Velocity 1.30 main at 48 lbs and Sync 1.20 cross at 45 lbs on a pro stock Blade 98 18x20 and it was so stiff that full bed poly definitely feels softer on this racket. Don’t know why but full bed Sync is super ok on most rackets I tried, except Babolat Pure Aero.Specifically that Sync seems to stiffen things up compared to a full bed of zero, or that snapback has reduced enough to mitigate comfort benefits from Zero in a full bed.
Did Sync in a full bed today in the CX400 Tour at 55/53lbs, no issues with comfort at all.
I’ve found the Whiteouts to be quite unforgiving at high tensions with stiffer strings. Dead ALU at 49/46lbs was just as bad at the too tight Zero/Sync, comfort wise.
