First of all the band looks great as is. I think the short coat looks fine but over time I'd fear the damage the coat would do to the horse hair sporrans or even if it wasn't damaged, just the extra maintenance it would take to straighten it back out.

A nice touch would be a short coat with a sporran cut-away, a-la http://www.glengarryhats.com/cutaway_cef.php but double breasted.



Add a pipers plaid to it and you will strike a very impressive image.
