Definately blag some RHS time, I did a Student Fly in with one of the Magazines a couple of weeks ago, and 2 hours of solid flying in busy airspace, whilst getting to play with some post-PPL toys (GPS, AutoPilot,, etc) was time well spent.
When I got to my lesson last week, my taxying was more natural, and I didn't have to think too hard about actually flying, it had suddenly switched into Subconcious
My advice for the circuit is to get settled early, get the checks done early in Downwind and give yourself time. Saturday was my first landing in a month and it was awful!!
