6 is the almost-180-degree hairpin left with a couple of nifty ripples in the pavement (but then, what corner at Cayuga doesn't have ripples in the pavement ...)
You actually don't want to be completely off the brakes before turning in. What you want to do for that corner is brake all the way to the turn in point then modulate the brakes off at the same time as you turn in. This is true of most corners on any racetrack that require braking before you enter them.
Why is this ... to avoid (or minimize) unsettling the front end. As you are braking, the fork springs are compressed. When you are turning, the fork springs are compressed. If the transition from braking to turning happens smoothly and simultaneously, the forks remain compressed throughout. This means the bike is not going up and down as you are going between braking and turning. It also keeps the bike in a nose-down attitude, steepening the rake angle and actually making it easier to turn in when it's like this. It also keeps weight on the contact patch so that it maintains traction throughout the whole process.
Obviously, that requires a certain amount of co-ordination (and a lot of laps of practice, to get the brake and turn-in markers right) and it's not going to happen while you are learning the track - but then, you are normally going a bit slower while learning the track anyway.
