Zorg, there is a school of thought, not that I myself buy into it that with a 1HBH a smaller head sticks yield greater rewards and conversly larger heads tend to benefit the 2HBH. Maybe, maybe not. Some folks base this off of better manuverablity with the smaller head raquets and that is something needed by 1HBH's. This is then vaildated by comparing pros we see on tour and their styles of play. I don't fully buy it. Now longer racquets might be better for the 2 HBH but that's another subject. Again there's always exceptions. Plenty of good pros have use larger racquets, had a 1HBH and has success. Paul Annacone used the POG OS, a bunch of pros with 1HBH's today use the PD 100 sq in head etc. I could name more like Shlomo Glickstien, Peter McNamera and Trey Waltke but I'll stop there.
Bottom line is I firmly believe that it's really a matter of personal preference. Go with what feels best for you. When you decide on a racquet make sure you are convinced it's what feels best to you especially under match tested conditions. Once you make your selection stick with it for a LONG time. Just my 2 cents. Best of luck to you.
