The decision is as much a budget choice as any.
The Norton 4/8K plus the 12K Super Stone are my
stones of choice for my shavers. Most days I only
pull down the 12K.

First in case your are tempted do not mix vendors unless you must...
one vendors 10K might be another vendors 8K.

Since you have a sharp razor now you can buy hones to maintain
the edge.......
