What size of cluster dictates chain size change? Even down to 6 cluster?

I'm trying to keep a larger chain, one of the considerations about 9 spd. I run a single chainring and I high torsion the drive rather than gear out when doing many types of cycling.

I've not snapped a chain since a kid, but don't want to..and just may when doing rock hopping.

I'm on a 7cluster, am building an 8 or 9.
I THOUGHT I read of a Sachs? chain that ran lower gears?

I'm get the cog spacing, but what can I go for now (even still on 7) that can do an 8 cluster as chain?

Also would SG cogs matter for building the 8 cogset? can I re-cycle them or should\will it be IG?

Sram is o.k. What is the Sram designation 7-8 and 9, in case I order?
Something more heavy or exotic is fine. No hollow\light chains I think.

I entered back into bikes during the 9spd phaze and am not familiar with what went on in drive upgrades?
Maybe I want to stay 7 speed - phat chain!

Thanks>jef.

6-7&8 chains are the same what will work for one will work for the others 9 speed is a bit narrower. I have good results with SRAM PC 58 and 59 chains
