Awesome! Welcome to the best game of all time!
People will tell you to get used to the keyboard, but after hours upon hours of playing THD with a controller, maybe your best bet actually is to keep your settings. I dunno. t2 IS easier with a keyboard, but I guess it's all about what we're used to.
Tips, hmm.. other than "don't fall" I'm not sure. The bike is a lot bendier than the Phoenix. It's slower to manoeuvre, and you'll soon find that many techniques that are common in HD won't work here. Conversely, there's a lot you can do with this incredibly fun and playable bike that you can't in HD. I always preferred the t2se bike, there's just this feeling that you can push it to its breaking point and do some really cool stuff. Not that you can't with the Phoenix, but.. it's just different.
I know you've had (or maybe still do? idk) world records on THD so there is good hope for you my friend. Many old HD players have made some impressive debuts on t2se in the name of familiarity with the genre. T2 is a bit more hardcore, I think this is accepted as truth rather than opinion these days, so if you can 0-fault all hard tracks before Evo is released, I know I'd be impressed!
Keep posting any specific questions you might have, we'll try to give you some good answers.
