No doubt THJ will cost the most of the 3 you mention.I don't know if he is using his own engines,but he's not been on fire anywhere,so I have read.Bit of a gamble over the others because of the cost involved I guess.I think i'd have Rose on 5.25 over Josh 4.65,just.But MPT over both on 5.20.All depends on the points limit.The silly season starts soon
