Then the ditch complex- for the BE90 its just a random ditch but for the PC ODEs they've been putting a skinny a stride after which really catches people out. I would practise that if nothing else, especially if he's likely to baloon the ditch its flipping tricky to hold them straight to skinny when they do! There's another double whichI would steady up for as it can surprise them a bit as theres lots to look at there- maybe practise going quicker and then really getting him back and concentrating. Then theres the run back towards the boxes and a couple more skinny types which jump reasonably well IF they're not peeing off home! And the last question I think is a chair fence, dogleg to wishing well skinny- if you start thinking how clever you are before this its likely to catch you out :L Also, ride the last fence as a stupid amout of people stop there!
Hope you have a great day with Reg too, I read all of your sisters reports and you deserve to! If the ditch to skinny had been apart of the BE90 there would have been uproar imo as it was just so hard for them to work out; being only one stride from the ditch made it super difficult as there was no room for manouver if they jumped even slightly too big at the ditch!
