i am going to be buying a new husqvarna,i will be using it for clearing trees around ppls homes and land, also for firewood cutting, and if i move to somewhere that has bigger trees, i would want an all around good saw, i was thinking of the 575xp, or should i go to the 385xp , or 395xp, or should i just go ahead and get the 3120 xp, i know that is probally to much saw and not needed, but i have a stihl 045 av right now, for my current saw, thank you
