con struct definitely gave you some sound, solid advice and I "+1" his thoughts.
However, if you're just looking for recomendations for good jazz sticks, Promark's Elvin Jones sig. sticks are great - a 7A size. Also, try Ringo's sig. sticks from Promark. They're not actually jazz sticks, but they are a longer 5A (they seem thinner too, but that may just be because the extra length makes them seem that way) and may serve as a nice transition stick from the regular rock-weight sticks that you likely used as a "heavy hitter". Any jazz drummer could definitely use these if they wanted something a bit meatier than a typical 7A.
