He stayed on well and the trip should suit him.'Twiston-Davies has yet to decide whether to run Naunton Brook in the Hennessy or send him to Newcastle for the WBX.COM Rehearsal Chase on the same afternoon.'It depends on the ground and one or two other things,' added the trainer.Knowhere is generally a 16-1 chance for Hennessy glory, with Naunton Brook 33-1.(C) PA Sport
