Well I've got good news for you then.
On the other hand, I really don't feel like diving straight back into this right away (and I did mention this before I left last week). For now, I'll update the table with whatever you come up with, and then maybe I'll come back later and have a real go at it.
EDIT: Okay, I couldn't help it. Hail 9 improved to 10:
Don't use the same lemming to build the whole bridge. Take a step back...
And Hail 15 can be done with 3 (your replay was actually very close).
And by the way, GuyPerfect did come back before leaving again.
