Is there multiple red dogs? I ask because the shapes-sizes appear different and I see maybe 2 colors of red. If there's 2-3 reds like a O, <> and a ^ those are good, I think ^ and <> has less casts, seems to carry the lines better. Red O has more cast but stays in the corridor. Blue O is a tad looser, Yellow O a tad looser than that (both get loose at the end, handler appears to let them carry). Other 2 color purple/maroon get loose in the beginning. If a blind is about control and staying in the corridor, and there's only 1 red (handler is micromanaging to stay in the corridor, style-perseverance points might be affected. Yes red had more casts (and he doesn't appear to carry them well) but he stayed tight though-out kept. If you have to pick a best bling either Red or Blue; just depend on what style you prefer and how adamant you are about your corridor. I prefer there be 3 red dogs, red ^ with 2 casts, red <> with 3 and red O with 4-5. And that's my ranking red ^ <> O, blue O, maroon O, yellow O , Purple O
