I’d be worried about getting a clean cut safely with 8″ branches. You can’t undercut first to stop an early break tearing a big strip off the rest of the tree.
You can stand right underneath and cut from both sides to minimise the tearing underneath, but getting your cuts to meet working at 6m isn’t easy. And for the final cuts, you want to be able to work at a bit more of an angle so the saw’s dropping away from you and you’re not under the limb. So you’ll need a longer saw than you on the ground reaching directly up.
Good fun though, if you like that sort of thing, which I suspect you do! I’ve had good results with a silky Sugoi taped and zip tied to a Darlac Expert 5m pole – the heavier duty ovalized one.
Great saw on a good pole, with a serviceable connection. A sight cheaper than a silky saw on a silky pole.
You might be able to bodge a replacement sugoi blade into the darlac mount, but if you were doing that, you may as well wear out the darlac saw first, it looks decent enough. I had the saw already and bought the pole for a different reason.
Take photos! Or get someone else to…
