I currently ride Junior in a flash bridle with a full cheek slow twist, but that is for jumping (though he rides really well in the slow twist on the flat). I can control him in a loose ring just fine, but I feel like he rides best in a full cheek slow twist. I would be using a nice fancy stitched bridle (no flash). Do you think it would be okay to ride him in the full cheek, or should I look for a slow twist dee?
Here are some pictures of Junior and I. I want to find the best looking show coat and shirt for us. I have no idea what color he would look good with...

Ignore me... xD My friend made me. Haha

This is the bridle he is ridden in normally.
His color changed quite a bit. He is normally a bit more coppery during the summer, but he dulled out a bit.
So colors!! And the bit thing.... Need advice.
