2 very different tracks, both Acc & grattan are fun as hell (anyone who says acc is boring isn't going fast enough ) Grattan as you've read is blind, 8 out of 10 corners are blind, some memory & guts will be needed for turn in etc. places i would watch in the early part of the day are the first right hander after the hump, coming out of the bowl & turn 3. If i remember reading correctly the first weekend is CCW, am i wrong there?
Would you (or do you) drive to a different track that was the same distance away as Grattan? CCW is that different track; all the blind corners you can now see threw them. You'll be surprised what you can learn about a track by riding it in the other direction. There were a number of regulars who felt the same as you, but now they like CCW more than the regular way.
Just my .02, Grattan is fun in either direction! I think it flows better CCW but you have to be aware that there's not much runoff at the bus stop.
