smithgd,
The PFA Coaching Scheme look to experienced instructors to provide training on PFA types. Unless you have extensive experience on PFA types, you would probably do better looking elsewhere until you have already done some instructing. PM me for more details.
The NPPL [SSEA] FI rating is probably worth holding out for. Otherwise, try a Microlight FI rating, and get some experience that way. There will almost certainly be a conversion to the NPPL [SSEA] FI when it finally arrives, including credits for the NPPL [Microlight] FI Rating.
The CRI rating also seems a good starting point - I am sure you would pick up some instructing at your local club.
Good luck whatever you choose.
Regards,
