I think they will increase the size of their team and perhaps produce a few more horses like deadsetlucky and goeslikehell.
Harness racing is no different to any other business, if you don't try to improve you will get left behind. It might mean that you have to make some changes to your training method or add some new equipment eg. race gig,swimming pond,walker or any of the other things that may give you an edge. The one thing that you can be sure of is if you sit back and do the same old thing you will be one of those complaining about another trainers success.
