I wish I could help you Ard. These GPS lines are not so available these days. Atop of that - the 7/8 is like the holly grail of speylines. Hold out as long as you can because they are out there somewhere. If you are willing to compromise though - take a gander at the Rio (who made the GPS for CND) PowerSpey: Only slightly shorter, slightly lighter, with similar long back taper and casting character. Clip the 7/8 and heavier weights at 20 feet for a set of 15'CD tips to match and you will have something close to the CND.
