I just recently strung up my Dunlop AG 4D200 Tour with a similar setup -- I used Pacific Classic Gut 17 gauge mains with Co-focus 1.23 crosses. I strung at 59/56 lbs on a constant pull machine. Played with this setup for the first time last night. What really jumps out at me from the get-go with this setup was the sheer power off the stringbed. I expected the power to be muted because I strung it up a little tighter than I might normally, but wow! Lots of pop from this setup. I was having a hard time at first controlling volleys and overheads, and even groundstrokes were sailing on me at first. But I quickly dialed things in and really liked this combination. Plenty of power, but also plenty of spin. I was serving non-returnables all night and getting lots of first serves in the box with pace and placement. Topspin forehands and second serves had lots of action, and volleys, when hit firmly, didn't come back. Can't wait to play with this again now that the stringbed has had a chance to settle in some and I have gotten used to playing with it.
