The ad is not there anymore. But I have to say I've never heard about the brand, so I wonder how is the quality. (not that I'm an expert , but I did quite a bit of research on saddles when I was looking for one for my own mares, and don't remember the brand Riviera to be mentioned anywhere)
English saddles are much harder to fit than western I think. There's a lot more that goes into it. I'm still learning about it myself. A one inch difference can make a huge impact on how it fits. Get exact measurements to make life easier. Make sure the channel is wide enough also. Posted via Mobile Device
I wouldn't recommend no brand saddle personally. More often than not they are cheap and junky. I do think GH has some nice brands to offer, so you may want to look into hers, or at least look for some better brands in your area (Wintec including) than no-name ones.
