Shaped pony girth

[Mari]

Which one would you recommend?
Pony has quite a forward girth groove & is very sensitive mare. I feel she needs the cut away space behind her elbow especially for when we start jumping. I'm looking for elastic & roller buckles on both ends & it has to be comfortable - she lets me know if it's not!

I would also like help with this, but a dressage girth rather than a normal one, and if I'm being really picky, in brown rather than black. Tekna does a nice one but it is black.
