New prospects?

Today was a good day. A GOOD day. With all the free time on my hands after none of the share horses came up trumps, being at home with the parentals isn't exactly thrilling. So any escape to Barnfield is much appreciated. Today I had a kind of assessment lesson from Charlie, which I every so slightly failed. But if I learn the ENTIRE book, maybe I stand a slight chance.
I rode Sienna today. I was meant to ride Tessie, but Sisi's shoes weren't ready in time. So I rode the tiny tiny tiny little spooky dippidy doo pony.
I swear she only spooks when I ride her.
As much as I loove her, I'm far too tall for Sisi. She is amazing, and such a cool little pony, and one of only a few ponies that I ride who need little kickish encouragement. But I feel... what's the word? Maybe a little bored, but at the same time frustrated, as if I can't do anything to progress when I'm on her compared to someone like Ada or Tess or Hols or Rosie. But maybe also I feel like I'm not bringing out the best in her - I can barely get leg yield on a dressage horse, and completely failed today. She's a beautiful, wonderful forward little Welsh, but I don't challenge her, or help her progress, or myself.
Maybe that's a good thing. I'm not sure anymore.
At the end of the lesson, I swapped onto Hollie for about 7 mins, because her rider had hurt her back. I hate to say it, but I have to love Hols a tiny tiny tiny bit more than Sisi, just because of her absolute cool stubborness. Whilst Sienna is somewhat finicky yet happy to please, Hols is stubborn and really makes you imaginative in the way you ride. (Also, her height and girth are far greater, so I don't feel like I'm squashing her. When I stood up so Sienna so she could wee, she kind of sunk into the arena. I am too BIG for her!)
Cantering Hollie around after I got off Sienna was very easy. Whenever these horses swap riders, they immediately think they're in trouble, so they're all nice and forward and compliant. As was Hollie, although I still had to constantly thumpthumpthumptaptaptapsmacksmacksmack to keep her from dropping out. I also ride her kind of gung ho - little or loose contact, huge, flappy leg aids, western seat.
Perfect for a BHS stage one examination, eh?

Keep your fingers crossed, Charlie knows a seemingly perfect horse that might still be up for share. Savannah....
So may the force be with me, so I can finally get my own (not really) horse. She sounds perfect. Here is her list of achievments:
Dressage
XC
SJ
Happy hacker (w/wo)
V. calm
Forward
Bombproof
Lovely temperament

Sounds good :)
