A tie rope halter is good for a strong/green horse because it gives you more control but the clip rope halter you can get wit a break away in case your horse does anything stupid and needs an emergency release. I would go with the clip rope because you still have plenty of control and there is away if your horse needs to they can break free.
What Kylie said the tie might take a few extra seconds buts it's nicer without the metal :)
tie :) I don't like the metal on mine
I have tie and clip. If im in a rush ide rather clip though...goes a tad faster.
