No personal experience but I've heard very good reports and my son plans to do one of their spin training sessions this summer.
There was a very good article in Flyer mag last summer/autumn which tells you all about it. This month's Pilot mag has an article about their aeros and combat flying sessions.
Funny thing is the Pilot article mentions all the Ultimate High instructors are top class experienced pilots. Then on the back page of the same issue there's an article about that pathetic little man Steve Moody from easyjet who caused so much trouble for them and including one of the pilots who's mentioned in the article.
