Carl,
As you are probably aware this years calendar is VERY busy indeed, we hav Ozfest this weekend, we need another weekend to work on the track, then it's the NE regional weekend.
At the moment that's all my tired mind can think about, but other than a ME regional (1 day) on the 26th July I'm not really sure how many other dates are free if you look at the Nationals, NE regionals and Euros dates.
So..... I'd say use it while you can if you really want to practise
