Well... imo a Wintec synthetic FQHB basically means it MAY fit your clothes horse...
In the real world, a FQHB should be wider in the gullet and possibly flatter in the angle of the bars then, say a semi QHB but it's kind of like buying jeans... buy from one store you fit a 10, another you keep trying til you just about burst out of a 16... I think there is supposed to be a standard formula for gullet widths and angles, but I have yet to find out the saddle makers that agree on it!

I'm sure Maria will be able to explain the technical stuff better... I just know the only synthetic that would fit my ever widening baby was a Weaver that Ray Cooper got in for me... he hates synthetics too, but agreed that it was best of a bad bunch if you don't have the cash for a "baby" saddle. Nice and wide.
I have to say... I have found an awesome CHEAP saddle over here ... I know some will groan, but it's a Royal King roughout with a "veriflex" tree... I love it. and more importantly so does Molly. Her movement has changed so much, and she feels so comfortable and relaxed in it.
First time I rode in it I had not ridden her since before she shipped out in December, and it was now near June... I put it on her, it looked ok ... that new saddle stiff thing had me a little concerned, but I stepped up, it didn't move despite loose-ish cinch, and I rode her for a bit, all paces, she loped off on the lead I asked for every time... she even managed a nice slow jog, and when I asked for a back up she dropped her head and rounded up beautifully... considering I was barely asking for this stuff as I had been unable to brush her back end properly cause she was having such a sore muscle day... I was thrilled!
And it put me in the right position, my feet are under me, which helps me get the weight off her back if she is a little tender... and keeps me on her back if she wants to test out my ability once in a while!
Every other saddle I have owned she would fight a little if she was sore because it wasn't helping her, but this one, even she seems happy to wear it. She doesn't wring her tail or give me dirty looks now when I cinch her up, and I am pleasantly surprised with the quality... it's actually really nice... which is weird as I am certain I have seen a Royal King that was like compressed cardboard... but anyway... I know it's not my usual standard, but it's a real nice saddle if you just want a work saddle you can trail ride with and not freak out every time a branch whacks it... which is alot over here!
Changing subject for a second... anybody use Equine America More Muscle? Well I do, because the stuff in it "gamma oryzanol" helps Mollys muscles alot... some protective thing, don't understand, just see it... anyway, in England I was paying 80.00 gbp +... over here... $21.00 yeah.. TWENTY ONE DOLLARS! Can you even believe that? 80. gbp is near enough $150 dollars...we are ALL in the wrong business people.
Still miss ya. Hope show season is going well. x
