It's a tough one.... It's not really just a matter of going whole hog or not. It's how you go whole hog... You say that you want to have more control over your brew, so I guess you want maximum flexibility...
That means that you may do decoction mashes, batch sparging, fly sparging, RIMS, HERMS, SWIG.... or any of the other methods... For this reason, maybe you don't want to invest in a system, because the system may not have the flexibility you are looking for.
I'm not done building up my brewery yet, but I'm not sure where its gonna go either, so I'm trying different stuff and as I recognize that I need something, or come across a suggestion that seems pretty good, I expand.
I know for sure that the RIMS system that I lusted after for years is something that I'm just not interested in anymore. (good thing I didn't plop down a couple of grand, huh?). You can probably reconfigure the system should you get one, but why get one if that's what you are going to do?
Am I rambling? I think I'm Rambling... I'm rambling, aren't I? Do you think I'm rambling?
here come's happy hour
