I'm done with my old Partner cut-off saw that I originally bought used. I'm going to get a new Stihl unit. My Partner was a 12" and I never minded the smaller machine. I like the smaller, lighter saw to cut pavers in place easier. We do a few SRW's and I just cut both sides of the block when we need cuts. What are some good reasons to get the 14" 420 over the 12" 410? Thanks.
