That is really kind of an obscure question. Different set-ups will feel different and different drivers will drive differently. I personally don't like to bog the car with low rpm's, so I typically cruise at about 2000-2500 and just shift as per the traffic situation and/or how fast I want to go. Its really left to personal preference and immediate driving conditions. I have a buddy with a very similar setup, and he likes to really lazily shift at low rpm's, sometimes not even using the clutch (rev matching with a worn T-5... surprisingly smooth if done right). I like to rev a little more, but i hardly ever even look at the tach unless I'm going full-tilt, and thats a different story altogether.
