@dancing james I have done this exact thing but I used angular ring nails for no other reason than I watched some youtube videos and the guys used the same. The way you overlap the shingles does mean you need a nail with a good grip - so ring nails are preferential.
I'm not sure those staples would have the same grip - maybe they would?
Spoke to that company and they said once the cedar dries out the staples are likely to pop out. There are paslode cedar staples but they also need a paslode staple gun which makes this far too expensive an option. Looks like it’s time to buy stainless ring shank nails.
2nd hand Paslode guns hold their value and there's a ready resale market - It could work out cheaper than buying a different gun or renting one. And certainly easier than banging in loads of nails by hand.
I picked up a Paslode IM65 second fix gun, which I plan to sell for £50 less than I paid.
