I have 3 year old gaited gelding who I may start showing western/gaited pleasure next year. We currently ride in a double rope nose sidepull.
I know the rules around here are snaffle if under 6, shanked if older thank 6, no gag, no combo bits, no twisted, no chain, no poky tortue devices, no mechanical hackamores, but bosals are acceptable. I have never seen if a sidepull is accepted or not? I wouldn't consider it a mechanical hackamore, but it's not a bosal either.
