Rump Rug Question

[RDCARRIE@aol.com]

I'm looking at rump rugs for my horse, and need some input on pros and cons 
of two types.  I want the kind that attaches to the back of the saddle 
(rather than to the front).  I've narrowed my choices to the Easy Bun Warmer 
(in the Sportack catalog) and the Horse Bums Croup Cover (in the Trail's End 
Catalog).  The Easy Bun covers a smaller area than the Horse Bums, which 
comes way down the sides of the hind quarters.
  
Anyone have any comments about either?  Does the Horse Bums (longer) type 
flap around a lot or get caught in brush?  Does the smaller (Easy Bun) type 
adequately protect the horse's hind quarters, particularly if it's raining?

Any input, personal experiences, etc. would be greatly appreciated.  Private 
replies are welcome to avoid cluttering the list, unless y'all feel that this 
is of general interest!

Thanks!
