I find for every day light house construction duties a 7 1/4" will do all that is required as most timbers are only 1.5 X whatever so handling a bigger heavier saw makes no sense and is just more weight than required. My two B&D Super Saw Cat 8" saws see next to no use. I am still running my 1975 and 77 era Makitas, they have been in continual use since purchased in those years and have only had one cord replaced though each one has gone through dozens of carbide blades. I have no use for a geardrive/worm drive saw, might as well just use a chainsaw for the limited amount of cutting I would do with one.
