In 1st gear starting out, I would definitely start by powering it up.
The cherry spot in 1st is about 5 grand... at it will come right up. It will come up almost anywhere in 1st, but you want to come up early in the rpm so you can ride it out a little longer. If your just starting out don't worry about the BP yet. Just get comfortable riding it out a little first.
In 2nd it will power up as well.. I just lean back and hit it around 7grand (you might have to burp the throttle) and it jumps right up. Stand ups are sweet but be careful because it will come up fast in 2nd. I usually bring stand ups up around 4-5 grand in 2nd with a little bounce. If you let the rpms climb up a little it will come right up no bounce for you at anything over 5.
But I would advise sit downs until you are comfortable with the feeling of the bike coming up...
