I think it is a nice bridle :) I ride in black tack, so I have done many a Jumper show in black and I have even done many a Hunter Schooling show in Black tack as well.
Heck, I am now at a very large, Primarily Hunter/Jumper barn, and I am the only one who rides in black tack. LOL.
I have placed well, in our shows and comps in black tack.
To be perfectly honest, all my bridles are "Dressage"/Eventing bridles, because I have a hard time finding Jumping Bridles in black.
But mine aren't double colored like yours. Just strait black.
The only difference is that Dressage Bridles are thicker padded - wider I mean. And then the nosebands get different as well, some dressage bridles you find Crank Nosebands *I dislike these very much* but it is a personal preference.
Anyways, I use Dressage Bridles all the time because they are black. Mine look just like this bridle, niltch the flash. I do not use Flash's at all.
So if I can use "dresage" bridles just fine while Eventing and doing Jumper shows and lessons and clinics and all that whoo haw, then so can you :)
