I've run a 24" on my 455 for about a year now. Extra reach for limbing and it cuts fine in wood up 18" (mostly elm, ash, and boxelder). It would get a little slow in the bigger logs when I was running it stock(12,500 rpm factory setting) but with a muffler mod and some cylinder porting it runs just fine. Just the same though if I'm regularly cutting any wood 18" and above I pull out the 84 cc. When cutting firewood on the ground the longer bar really saves on your back! Just keep in mind where your tip is and don't dig any dirt with it.
