A big saw will work when you need a small one better than a small one will work when you need a big one.(paraphrased from the Fabulous Furry Freak Brothers)yup...i can relate...i only have 4 saws in my truck now..660, 046, 2x 460's...
which brings me to something else...people often ask me why i run such a big saw....and it is as simple as this..they may be heavier..but you don't have to be there as long!!
