If I still had my gorgeous Cybele then I would choose Lucinda Fredericks for her - Brit's attitude and movement are identical to that of Cybele's.
For Boo I would choose WFP - firm yet tactful riding needed! And she is only 15.1, so it might be worth getting WFP to ride her just for the comedy value!
Andrew Nicholson for eventers... you can just SEE him giving a youngster confidence. He is totally there for them...or WFP. Dan Neilson is a fab, sensitive rider..wd defo go for him show-jumping.
For eventing Harry Meade or Francis Whittington, for SJ it would be William Whitaker or John Whitaker and for dressage I would like to see Stephen Clarke or Chris Bartle on Sov. I wouldn't subject the oher 2 to anybody!
Definitely Mary King for eventing - she is a great rider and seems so kind to her horses - I think she would really bring Molly on nicely without stressing her.
For showjumping - Tim Stockdale - he just seems like a really nice guy and makes the most of horses that are not top ability.
For dressage I am sure no-one would want her, perhaps a circus trainer or failing that Carl Hester. Not 100% sure he would have enough patience
