ok..i've been searching the crap outta the site all afternoon and i can't really find a good answer for this. i've got a 460 on the way and i can't decide what size bar i want with it. i'd like to have a 28 for when i need it, but what is the best bar for the saw to "live" with? would a 20 or 24 be better all around, or would the 28 be a good all-around bar for it? would there be a point in having a 24 and 28?
