I like the confo on the Gray better (but then again, I'm biased to Gray Appendix horses! Lol).
But you would get a heck of a deal with the paint. Depending on how high you want to jump, she may have maxed out (she's barely clearing, and she looked a little like she was struggling - her front tuck was uneven). Do you have any confo pictures of her? It would be easier to compare the two with similar photos.
Well as far as I can see the first one has a nice tuck. She did over extend in the 1st jump but it doesn't look like it in the 2nd.
The grey looks way better built though... Both are beauties and I think you would be happy either way :)
I personally didnt like the paint as much at the trot (which really doesnt matter for jumpers, just MO tho) but she is *CUTE* o/f. I also happen to loooove her color, she's eye catching. They grey is conformationally cuter, I think although it's hard to compare the two with out seeing the grey o/f. The paint is very focused on her rider and very alert over the jump. And a good price for her, I think.
