Does stringing with the O-ports give the old Rebel 95 much more pop than the string holes? I like the Team version a lot with the o-ports, can really get some speed to put away flat balls and love the big sweet spot and feel. Only prob is I've lost at least 10-15mph on my serve. I picked up a regular Reb 95 which came with string holes. It seems to have more spin but less zip on flat balls. Before I cut out the nice natural gut it came with to try the o-ports I'm wondering if anyone can confirm or deny my speculation that the o-ports give more "launch" on flat balls. Reb users?
