I generally use a pre-soak with a bit of wetting agent, and the 
8-reel tank is the reason I started (Nikor tank and reels). I had a 
job in the early 70's where I shot 10-20 rolls a day, and I had to 
develop and contact them.

With an 8 roll tank it's also important to have a development time 
that's about 10 minutes or so, and that develops close to exhaustion. 
A too active developer that needs only a short time is likely to lead 
to streaking. A one-shot setup is best. I use Xtol 1:3; that allows 
me to develop 7 rolls in an 8 roll tank.
