I am torn now between the SC GP and a TG T6.
She was happy for me spend as long as i wanted riding round trying different saddles, and did a very thourgh fitting assessment first as well. I was very impressed. I have heard good and bad things about the person i used, but in my opinion , she is a qualified master saddler and yes, I had to pay £60 for fitting, and £15 for travel (which is what ive heard some gripes about) but if you get a professional service from a properly qualified, non biased person, it's worth it IMHO.
