I don't remember riding in one, but I sat in TG in Dover, and it felt good (although wide). Thorowgood seems to be a good fit for wide horses. I believe Golden Horse got one last year, so you may ask her.
As for Wintecs there are SO many used ones that you can find a really good deal. :) I tried one too and it was not bad, just not a good fit for my mares.
Good luck in your search! Finding English saddle that fits is a real pain at times.
