Would make perfect sense to me to be honest.
He has mentioned that they could skip cheltenham altogether with brighterdaysahead but I cant see it. Wouldn't make sense to not bring her if shes fit and firing, she's already shown she can run her best at aintree after going to cheltenham so no real need to be keeping her fresh.
If you were to ask me right now id say elliotts best chance of winning two races at cheltenham with those two are bda in the mares and wodhooh stayers. Bda is probably classier than wodhooh and even better than her at the mid trip, and wodhooh shapes like one that could be even better over further. Couple that with teahupoo being beaten back to back in the stayers, they probably dont see him as being a favourites chance in that anymore.
One injury to lossiemouth though and I'd say bda would be champion hurdle bound again. Or even if the ground came up very testing, I think it would narrow the gap between bda and lossie, while also making the mares trip more testing which would suit wodhooh.
