I'm positive I've asked this before, but I couldn't find anything

Since I'm going to starting working with Pinto from scratch again, I though I would just talke a look at everything and make sure it is the best I can.
For those who don't know... a potted history

6 years ago Pinto came to me with a full cheek snaffle, which was quickly changed to a full cheek french link, which was changed to a hanging cheek, then we went bitless for a year, then we went back to a bit a Neue Schule hanging cheek, then we changed to a loose ring single jointed snaffle for a while (to humour my instructor - I knew best and we both hated it). Most recently I've been riding with a Myler copy, a Western D with copper inserts, but once again Pinto is fussing. the vet had a look at his teeth and proclaimed they weren't bad, but he would give them a quick once over when he comes back in 2 weeks.
I would have preferred to go back to the NS bit, except it has gone walk about, and now I'm not so sure if I should replace it, or try something a bit simplet like a NS verbindend/starter or team up bit.
Does anyone have any experience with these bits, or any other words of wisdom to impart?
Thanks
