The only worry I would have with D&L is whether they could get beyond romantic programs. I think Paradis/Ouellette had the most successful choreography from them -- they were enchanting -- but it was the program I could mostly see D/L skate to, which is often the case with skaters turned coaches and choreographers. I get a similar impression from Wing/Lowe's teams. I didn't get to see the Junior FD's, though, and there may have been some other styles with which they were successful.
Is there a waiting period for getting subsidies for being a Quebec athlete? If not, D/L could be a way to move to another coach without having to pay for everything from scratch. I don't know what Ralph and Hill's other lives are like (if they're in school, if they have jobs where they are), but if they're willing to re-locate, D/L might be the best option.
