My girlfriend has been asking for a pair but after much searching I can't seem to track down a pair in size 4 - they told me at Olympia and a local saddlery that there wouldn't be many around until March time....
Sorry not much help on the original topic - she did ask for the Dubarry ones...
I think it's ok for them to have a rest a day after a show and then basics to keep them ticking over and fit during the week.
They shouldn't overdo work at home or they tend to get stale.
I don't think a day off is laziness at all. Depends on how much work the horse needs.
