Already done to all my reels.
Calcuttas tend to improve quite a bit more than other reels after a nice super tune.
Now, all you need are Boca Orange Seal bearings from BocaBearings.com. I just installed a pair in my Daiwa Sol and man can this thing pitch. Totally worth the $30 especially for someone like me who is trying to force a FW reel into a dangerous Cali SW environment. They are ABEC 7 bearings with orange rubber seals to prevent crap from getting into the bearing.
