I think you mean waterloop ties.
I wouldn't think that most judges would even notice, especially at open shows, or that if they did they would knock you for it. If anything, you're using something OTHER than scissor clips, which put you at risk of losing a rein under certain circumstances. While window shopping I've never seen show reins with waterloops, but I used a lot of clean, well fitting basic tack at my last show and it didn't seem to make too much of a difference. (To be fair though, my horse is NOT bred for WP so I'm sure that had way more to do with our standings!
