I have owned two straight tails. T-tails may be a bit different than what I've put here:
1) When doing your transition training, definitely do a few trips around the pattern at max gross. She flies a bit differently at gross than at "standard training weight."
2) Related, do NOT rotate early when hot and heavy. You can easily get behind the power curve. Be very dedicated to flying by the numbers, particularly in these conditions. Approach/landing is pretty forgiving.
3) Try some takeoffs with a notch of flaps and some without. Personally, I like the feel better with a notch. Without, it seems to skate around a bit at near rotation speed.
4) Depending on how you plan to fly it, you might want to generate some weight and balance sheets with/without some of the seats just to have on hand. (Assuming you have the quick release ones.)
5) Never try to reverse the gear until it has cycled fully. The hydraulic power pack does not like that at all!
