When Brandywine was racing many years ago, I had a trotter in to race one night and in the paddock next to me was a Swede. I can't remember his name but after talking back and forth waiting to race, He mention to try and take the front shoes off to help with a interfere problem I was having behind. Turn shoes around in front to jog and train but on race night remove them.
And BINGO! $$$
True story!
