Hi Whirly,
I would love to do a PPL(H), but have not the money - FW and doing IMC making me too poor!!!
Had an hour's introductory lesson at Sherburn a few weeks ago, though, and found hovering 'interesting ...'! (There was, apparently, some improvement during the session, but I too easily got into an oscillation and had to re-establish!)
Still, better not go for another lesson too soon, otherwise it will be curtains for the bank balance.
Good luck, though, with finding students: there must be many wanting to take up hovering.
Best wishes.
