In reply to Will_Thomas_Harris:
I don't think warmth will be that much of an issue. I saw a guy climbing the Mini Moonflower in Baturas in early June last year. I'd have thought they'd be fine if you are only doing day routes.
I presume the reason you want to use ski boot is because you don't want to shell out for Spantiks or Phantom 6000m.
I've never climbed in Ski boots but I imagine it would be way less fun than climbing in climbing boots.
If I were you I'd buy a second hand pair of spantiks or a pair plastics and some good gaiters (OR Crocs).
We skinned into the routes with a big bag on our backs and changed into climbing boots at the base.
I've only done the first 3 pitches of the Mini-Moonflower. It got warm so we bailed. It loots great and the crux sounds fun. There is a great route to the left of it called Bacon and Eggs. It's a big long Scottish IV/V style Gully. More sustained than the Mini-Moonflower, but a bit easier I think.
