I love the 9T, it doesnt really excel in any catagory though.
Its a tough plane to be succesful in 1v1 situations, but when you have a partner or are mixed up in a furball it can be a really fun plane to be in. I have had some success hunting bombers...however at high altitude and slow speeds the nose is really hard to keep still. It gets pretty wobbly if you try to maintain a 1.5k distance from the bombers. The center of the bomber is obviously the easiest part to hit from that range but I have much better luck taking them down by aiming for one of the engines. At 1.5k it seems 2 hits in one area will either take the wing off or set it flaming. 1k range is really easy to hit, its just point and shoot, at 1.5k you start to get alot more lob in your shot and often times the round will fall just in front of or behind the wing.
With tank killing I have alot of success against panzers. I have killed them with 45 degree dives into their turret rings and with single shots to their top armor from a 90 degree dive. Panzers seem to go pop easier than M3's. For some reason M3's always take alot of rounds from my 37mm to kill.
