what is wrong with running a shorter bar? nothing. i run an 044 with a 20" all the time. cutting up to 30" trees. for the small stuf he is talking about, 6" to 14", similiar to the aspen i cut, a 16" bar is perfect, hell shorter would even be fine. i read that you guys are running 24, 25, 28 on a 460, why? are you cutting really big trees? i only run a bar that long on my 066 when i need to buck logs into firewood, and then only when i am cutting logs over 20" a 24" bar has more teeth to sharpen, takes more power to run, usually sticks out the other side several inches, is more weight to carry in the woods, and the chains cost alot more. use only as long a bar as necessary.
but i guess a short bar just doesnt look as cool
