Had Billy been totally trashed in NC due to bad jumping, this might have come up before. FAct, he's battling for podiums at the highest level of his sport.

There is the Biathlon thing indeed...

Semi-related : Carolina Kluft has decided to quit heptathlon, and is representing Sweden in Beijing on long jumpo and triple jump (the latter totally new to her). She is the best heptathlete ever.

From indoor testing, the US ski team probably knows really well what Billy's numbers are compared to the XC-onlies. Billy being as good as he is, that should translate decently into predictable snow times. It's not like they're being tested when running or cycling, Billy can inline and rollerski like no-one's business and I think is tested in the same way as the XC team.
