Both jumpers are set to start favourites on what is expected to be a very wet Riverton track. It was rated a heavy11 yesterday.
Wild southern weather has pounded the Riverton course this week, and conditions will be extremely testing.
Higgins said he had no concerns about how Banbury Lad would handle that challenge in the Great Western Hurdles.
"The wetter, the better for him."
Higgins will seek a hat-trick of wins with Banbury Lad in the 2500m feature.
The jockey said he saw no reason why the horse could not continue his excellent recent form.
"I would be disappointed if he didn't go another good race."
Banbury Lad has missed only a placing in six starts over hurdles when over-racing badly in last year's Great Northern.
The Energizer and Go Go Gonzo look Banbury Lad's main rivals.
Higgins said the wet track could bring Doctor Eden into contention.
The jockey is confident Tai Ho will relish the heavy track in the Great Western Steeplechase.
"Riverton is incredibly wet at the moment and if anything I think that will help us."
Tai Ho will again clash with Delacroix and Adequacy, who beat him home in their last starts.
Higgins his hopeful a turnaround in weights will help Tai Ho.
The Gore jumper had to carry 7.5kg more than the winner, Delacroix, and 6ks more than Adequacy.
Tai Ho's 69kg handicap means he will carry 5kg more than Delacroix and 4kg more than Adequacy tomorrow.
"He has less weight - he had 70kg last time and he is down 1kg.
"I think he just plugged a bit under the weight last time," Higgins said.
