Great questions!

1 - I'm not sure. I wonder if it depends on the halter used (english-park or western-square), attire (english or western) and of course what the judge wants. Sorry, not much help here.
2 - When I get my horse I'm paying for the TAP download! I want to know too!
3 - pasture boarding? I've heard some horses don't crib when pastured.
4 - Not sure on this one. I haven't used either, always had easy keepers.
5 - I have had horses on shavings and dirt. Shavings was in a boarding situation so I really couldnt bed as deep as I wanted, but at least the horses weren't getting cast. Inevitably the stall cleaners felt it best to MOUND up the shavings in the middle of the stall Helloooo...casting hazard! Esp in smaller stalls. ugh!
6 - (best question yet!) Probably my saddle. Passier GT dressage saddle. I like to keep it simple: snaffle bridle, saddle, maybe dressage whip. I do love a good lounge line my fav was flat wide woven cotton with a chain. Gloves are another must, helmet too

Use your talents, that's what they are intended for.....
