So I think I'm going to pick up a PD Roddick GT. What I'm trying to decide, though, is whether to get the GT or the GT+. I've never played with a + before, and I have some questions: Besides just getting used to the extra length, are there any disadvantages to + versions? I can't think of any. I'm vertically challenged (5'6) so the idea of getting a little extra leverage on my serve sounds appealing. But I'm wondering if there are trade-offs I need to be aware of. Your thoughts? I'd especially like to hear from folks who have recently gone from regular length to +, or vice-versa. Thanks!
