What do you ride your Kiger in? There is a lot of talk that they have a low pallet, and so some bits are not well suited for them. I like to ride in a regular snaffle for some and a dogbone snaffle for my others that are picky about the bit. In preparation for showing, I've also transitioned my stallion to a short shank low port curb with a solid mouth piece, which he is doing well in. I hate that we have to ride horses over 5 one handed in a bit for most shows, even if they may not be ready. ugh!
Oh I also love riding them in a hackamore!
