before you decide on a flash or drop or fig 8, i ask WHY do you want one? what purpose does it serve for YOUR horse specifically? i'm a strong believer in riding in minimal tack and accessories whenever possible and frequently school my hunter pace/jumper in just a mullen snaffle, curb rein out of use, no noseband at all, no martinagles, etc.
if you want something for LOOKS, i ask you to PLEASE first learn about it's EFFECTS on horse and rider.
using unnecessary tack imo is one of the best ways to teach a horse to evade the aids. and one of the hardest things to correct.
i always tell my students unless you can give me a good solid honest reason that is 100% sound and convincing as to WHY you use the tack you use, i make them stick with a basic cavesson, bridle, reins, and bit.
even my hot hot hot hunter pace/jumper who goes XC in a 5pt breastcollar, running martingale, ad fig 8 goes at home in what i said above - mullen snaffle no accessories, at all. why does he use them XC? because he is hot and when we're on a 12 mile hunter pace jumping obstacles 3'+ that are solid items all at speed, i want the emergency brake there if i need it. good thing is thanks to the time and training i put into him without any of that stuff, i rarely (if ever) need it.
