I'm looking to get a saw that will handle a 24in bar in hardwood, with authority, & using 3/8 chain. Seems to me that a 70cc saw is best suited for the task, but, judging by many of the vids & the praises heaped on the 562, it may be just the ticket. Is this asking too much for a stock saw? Would it be wiser to have it ported, or just accept that I will need a 70cc saw & the additional weight that comes with it? In years past I handled a 920 Jonsereds with a 24in bar, but am no longer comfortable with that much weight (power head dry was 17.5lbs.).
