Personally I'd recommend doing Wilde Maus (£6) (it's surprisingly speedy and the 2 big drops are fun), Air (£6), Showtime (£5) (I thought the Afterburner would be lame but it packs some serious Gs and lasts long), Alpen Hotel and Blizzard (was either £6 or £8, can't remember) (it may be just another Booster but I THINK it's the medium sized one? Anyway we had a good cycle with high speed and lots of full flips)...I've also heard good things about that pirate walkthrough so that could be worth checking out.
