Yeah, swapping the wood round is probably quicker by the time you've undone/redone the screws to flip the saw round
I do agree with Bad Boi above, a cordless circular saw is excellent and that Dewalt is great as long as you have big batteries.
I do sometimes wonder if i wished i also had a cordless 18v mitre saw but it's in a weird bracket. I can't justify having 2 mitre saws but at the same time the i don't think i could go back to a 184mm saw blade after using a 255mm.
