The biggest problem with unruly racehorses that need all the gear is the way they were broken in and educated by so called horsemen that just look for the easy way out to fix a problem instead of educating the horse properly in the first place there are very few true horseman in our industry at present plenty of good trainer's,driver's etc but not horseman these are few and far between IMO
I'm with Don i think all horses should be ridden when broken in easy to control them on their back all we've done for 90 year's ( the family ) is ridden them from the start and find the horse's are better educated overall with the odd exception to the rule.
