Torque is king, but when felling sketchy big stuff I need speed as well. Chasing a barber chair, or out cutting a barber chair is one big reason. Bucking wood I need torque...
3/4 wraps I cannot live without any more. There are on every saw I own larger than my 261, standing at the stump it's so nice and comfortable when felling where you only have access to one side of the tree. Except for driving the mini over a stump, I never need to cut a stump lower than 4-6" from the ground, let the grinders the rest of it
Talking with my neighbor, retired career logger...he would run leaner for chainspeed on a patch of alder, and richer for lots of long grunty cuts in big wood for cooling and longevity.

Full-wraps are like having power-steering versus manual. A sharp chain versus groundie-sharp.
Above 261, full-wrap, here, too. I have a basically new Husky from Treebay, collecting dust. I didn't realize its a half-wrap. Haven't bothered with it. Kinda forgot about it. Should get it fixed up with a full-wrap. It's neglected.
Clean-stumping technique, shared at the Brand X forum, plunge in, keep you tip buried, chase around the stump. You're always pulling out of the stump, never pulling into it. Dirt pops off the bark being torn outward, not dragged inward.

For alders, wrap a chain as tight as your can into a grab-hook, pop a coupe medium to long wedges to tighten the chain. Easy peasy, ANY size. Chain-binders are a PITA. Wedges are durable and multipurpose.
