Rated ST and Bows

[Expy]

I was reading over adventurers last night, brushing up for another go at running an online game and making some pregens to knock the rust off when I noticed a little rule in the equipment section and it went something like:

'crossbows and bows use their own rated ST for range and damage, the ST listed is simply the minimum required to use one. For crossbows, rated ST higher than the users own means longer reloading, for bows treat high rated ST as if you were wielding a weapon with low ST'
'You can use weapons with a higher ST rating than you own, with a cumulative -1 to weapon skill per missing ST and an additional FP cost at the end of combat also equal to missing ST'

Correct me if I'm wrong, but that makes 'greatbows' rated for 19 ST (2d-1 thrust) usable for a starter heroic archer with say 14ST, assuming you're ok with the -5 to hit and 5FP cost per fight? I think that could make for a cool character; Very Fit to offset some of the FP tax, Weapon Master to add boatloads of flat damage, Telescopic Vision to offset some of the penalty? Flavoured as a half-ogre mammoth hunter from the freezing plains or something. You could stack a lot of raw damage that way.

I've seen this rule used all the time for crossbows, but never for bows. Definitely a bit different from the usual Scout thing of machinegunning arrows through eye sockets! If it is supposed to work like I think it does anyway. What do you guys think?
