I won't even try to pronounce his name Pricewise - Roigean Rua (spelt very badly), backing him ante-post could be a good bet IMHO.
The race has been run three times (Rockview NH Flat Race) according to the RP Stats. Mullins has the three winners:
2006 - Freds Benefit - won by 15 lengths (18 ran). Ran at Cheltenham 16th of 23. Horses were all wrong that year, Mullins ran 4 and the best he could manage was 12th. SP 20/1
2007 - Fiveforthree - won by 7 lengths (20 ran). Ran 5th of 24 at Cheltenham, beaten 3 lengths and badly hampered by Crocodiles Rock on the home turn. Mullins ran 3 (Cooldine and Mad Fish finished 7th and 8th). SP 16/1
2008 - Cousin Vinny - won by 1 1/4 lengths (20 ran). 1st of 23 at Cheltenham. Beat Corskeage Royale by 3 1/4 lengths. Mullins ran 4 (Lilywhitedancer, Apt Approach and Drive On Regardles who finished 5th, 6th and 20th). SP 12/1
Clearly a race that Mullins targets and the two years that his horses have been fit and healthy he's won it or gone close. Got 33's about Fiveforthree pre-debut in 2007 and then 25's Cousin Vinny last year pre-debut.
Might all be a big coincidence mind
