I haven't reached skiing yet with the beta adjustments, so I can't comment on those (for the stable version I gave up on skiing as I found the increased compounded endurance penalty from the extra weight of the skis caused skiing to be worse than walking after only a kilometer or two). I hope the adjustments will make skiing the better option.
A significant different between the old time/in game ski stick and modern ones is that the old version used only a single long stick (a bit like a sesta) rather than the current day meter long pair of slender thingies, so to quickly shift from a ski pole to an arrow you'd either have to release the pole (causing it to fall to the ground and potentially scare the prey), stick it upright into the snow (similar issue), or lean it against your body or a tree (with a risk of it sliding and falling, potentially knocking at your bow in the process for the body case). On the other hand, the noise you made skiing up to that position ought to be louder than sticking the pole into the snow...
So far I've rarely used bows to hunt animals (bows are extremely useful when "hunting" marauding Njerps, though [with bow and ski stick mismanagement leading to the death of one of my characters]), as I tend to endurance hunt them (and I usually fail with predators, but I usually avoid actively hunting those, as they're dangerous [which goes for the piggies as well]).
I think I've had some success with javelins, although I tend to avoid that as well, as it damages the skin, and endurance hunting has worked well.
I guess it very much depends on which ski hunting method you use. If you ski around and suddenly see a suitable prey at a short distance (possibly by zooming in) you may have to react quickly and probably use javelins. If you try to sneak up on prey they shouldn't bolt just because you're stopping. However, moving towards them and decide to attack as a reaction to them bolting is probably not the best tactic (as opposed to moving towards them, saying: this is close enough and then shift to the bow).
Open terrain probably favors bow and arrow over javelin.
A lot of rambling of dubious value...
