Hi

  I am looking into moving towards gaining some tek diving qualifications, currently I am certified to dive to 40m and use nitrox from 21% upto 40% through padi ( rescue diver ) . My main reasons are that I would like to use staged decompression and use higher nitrox blends for these deco stops, I like wreck diving and so these along with advanced wreck skills and possibly a deeper depth rating would help me get the most out of my diving. But I cannot decide which agency would suit me better as both tdi and iantd offer courses which cover these things, later I would want to progress onto using a rebreather ( probably inspiration ) though again this can be gained through either, is there anyone out there with any feelings on the subject ? If so any help would be apreciated.
  I know there is also DSAT though it seems a little more limited in the choice of courses on offer.

thanks
James
