She will be riding arena flatwork and flat trails with few obstacles. She wants to feel secure and comfortable. She has short legs, and her horse is medium/wide to wide.
Any suggestions or personal experience that might help guide us towards a more VSD-type flap with straighter leg-position or a more A/P flap with more forward leg-position?
My riding style, body type, and the terrain I ride is very different from what she'll be doing, so I'm little help to her on this.
