spool weight difference

So I was looking at a for sale ad for an 8 3/4 clutch sure grip as well as the cone and thought, that clutch sure grip looks massive. I have a lock-rite which is smaller than the clutch unit but am curious what people thought after going spool
Are you currently running the lock-rite? If so, how about a review?
I should put a spool in my nine, but my friend/nine inch specialist passed away, and I can throw in a lock rite in without pulling anything apart. Summers bros. axles I want to re-use.
