Which Brooks saddle?

A writer sits all day. My bum gets awfully tired. When I go on my
bike, I want my bum soothed, or at least not further bruised. I'm
thinking of getting a Brooks saddle to replace my Cheeko 90, which is
getting a bit tacky. (The alternative is to recover the Cheeko 90 in
honey leather of which I have plenty, though I don't know how it will
stand up to weather as it is off indoor Swedish furniture we trashed
so I could use the seasoned wood for my geribike experiments.)

I ride an hour a day, two hours a day for longer rides, never more.
Total mileage in the order of 2000m/3200km per year, creeping up
slowly.

Which Brooks model would be advisable for a guy who weighs 215 pounds?

Should I prefer one of the models with helical springs at the back?

Would one of the "aged" models give me a headstart on comfort.

General advice and personal anecdotes equally welcome.

I thought that I might get those Brooks edgewise leather-circle
handlebar grips that Jay Bollyn mentioned last year to match the
saddle. Opinion?
