OP said up to 30", there's no way you're going to see me using my 346XP on something like that, but I do have choices. I love the 346 and used it today, cleaning up tops from trees that I downed with my 390XP. From Husqvarna website describing the 346: "New edition with increased power and new design. Ideal professional saw where users demand rapid acceleration, maximum power and maneuverability. Excellent saw for high speed limbing and cross-cutting applications. Also perfect for felling small diameter trees." SMALL diameter trees!
