Mainland??? 
1) It’s an Irish sales race.
2) There’s an open bumper at Aintree this weekend with a decent purse.
3) English trainers could be forgiven for believing that the Irish bumpers are more competitive.
4) It’s a long way to travel with an unexposed sort.
With the above considered, I’d say three is a decent turnout.
As a side note, it will be very interesting to see how Henderson’s unraced but well-bred Snake Eyes gets along. Especially when considering the fact that Nicky isn’t mad keen on bumpers at all.
