"I have heard it will certainly make flying a self-launching glider easier - AFAIK at present anyone wanting to fly one of those needs an NPPL,"
cats_five, please excuse me for being picky: changing licencing won't make flying a self-launcher any easier, or any more difficult. The aircraft, the flying challenges and the vast amount of fun to be had will be all be exactly the same.

Yes, you are right - I should have written 'get licenced to fly a self-launcher'.
