Sky Bet cut the winner to 12/1 from 16s for the Cheltenham event.
Mullins said: "That looked very good and it was a nice progression from his Gowran run. He can jump, gallop and stay and I don't think you need much more!
"I don't know if he'll have another run before Cheltenham but he's on the short-list. He missed one or two hurdles but I think it was because Paul was trying to settle him - he might prefer going on a bit faster.
"It's hard for a four-year-old on only his second hurdle start to go out in front on a big open track with no rail but we decided to make the running because there didn't appear to be a lot of pace.
"Paul said he picked it up after two out and came back on the bridle. He's very keen, which was a feature of his flat runs, and I was hoping hurdling might settle him more, and I think he will settle with more racing."
