Question Alloy rear sprocket, yes of noooo?

Hi Guys
I've got a CBR600f3 97.
It's been a year long build so far, but I'm nearing the end.
I'm curious about using alloy rear sprockets these days.
I know they will wear out faster than steel for sure.
BUT, what I don't know is, can I just put another one on when it wears out, but with the same chain?
I'm thinking the EK 520 GP chain will be far tougher than an alloy sprocket, so should fair well?
No it's not bling, yes it's for reducing gyroscopic weight.
I already have Ti bolts on the front and rear disc, and alloy (with steel insert) sprocket nuts from
I will be getting a drilled front sprocket, the EK GP 520 chain (conversion I know), and either alloy or a Supersprox steel and alloy sprocket.

I know already what the general thoughts will be, but I'm wanting to know how many of you have done this, and did it turn to ****....or gold lol.

Before anyone says anything about wasting time on weight loss for an old bike.....
So far I have dropped 9kg (19.8Lb) off the bike, so yes, it will be enough to notice

Yes I ran a few aluminum sprockets per the 20k or so I get from a chain. Got old, fast.

so it didn't affect your chain life at all then?
If not, that's good news to me

My last aluminum sprocket Looked great 30k+ later when I sold my f4i! I ran a vortex 60t

This is a pic of it right when it was around 20k miles. I even ran the cheapest chain I could find, "KMC" brand from ebay for $68 shipped.

All about keeping your chain clean, lubed, and properly adjusted!
