I will be showing a green pony in hunt seat at an open non-rated show, The show is all ponies, and I will be competing(I really shouldn't call it competing as it is more for experience) mostly against younger kids, inexperienced riders, and green ponies. However the pony I am riding has a tendency to be kind of flighty and has occasional melt-downs when something is extremely overwhelming. She doesn't try to be bad but has had a rough life(before I could think of starting her under-saddle I had to get her not to freak out if somebody touched her or waved at her) So I want a little more control if she gets scared out of her mind(she is getting used to the unexpected but still spooks at times).
I was planning on using a pelham with double reins using only the snaffle unless I need the curb rein. Yes I know how to use double reins, and I have used them before but not on her.
My question is can I use a pelham on a green pony in an open show in hunt seat? I normally use a french link loose ring on an English bridle or a half-cheek driving snaffle on a western bridle.
