Nicky Henderson still undecided over Whisper's Cheltenham target

Nicky Henderson admits to being in a quandary as to exactly which race Whisper will be aimed towards at Cheltenham next month.A high-class hurdler before switching to fences for one start, the Dai Walters-owned nine-year-old has returned to novice chasing this season, winning twice at Cheltenham, most recently in the Dipper Novices' Chase on New Year's Day.The Seven Barrows trainer said: "I do keep umming and ahhing. I've always thought he was a JLT horse, but a lot of people are trying to convince me three miles might be better."I want to talk to Davy Russell (retained rider for Walters), he can advise me on what he he thinks."If he is nearly favourite for the RSA that tells me something about the race. We have Top Notch in the JLT, but it is not the case that one horse makes a difference. It is a close call."
