Pete G is fantastic... I had a few trips with him on my IR.
The school itself is very good - I had no complaints. Availability of the a/c shouldn't be too bad - the Tomahawks are used by PPLs at weekend but the Arrows less so. Try to have a word with one of the instructors and make sure they're happy coming in at weekends - most work mon-fri as it is. Otherwise I have no complaints.... they got me first time passes in both my CPL and my IR.
