Matt - Yes, as you stated, but I just wasn't sure about using two vessels.
Catt22 - I knew there would probably be a limitation with the 10g MLT with a 10g batch size. However, I was comfortable relying upon a bit of DME\LME to compensate. A larger MLT will be in the future. The MLT will gravity feed into the top of the BK; from the BK, the sparge water will go to the March pump back up to the Blichmann AutoSparge. You are correct that the top of the MLT may interfere with the AutoSparge, depending upon the grain bill.
I had not thought about the temperture loss during recirculation...good call. Perhaps foregoing the recirculation and just start sparging from the BK?
JonK - I pondered that idea, but didn't have a food grade bucket\fermenter\suitable vessel...and if I have to buy that...well, you know how it happens.
Thanks for all the insight, guys! It will be a little while before I upgrade to an appropriate HLT, MLT and stand...the 15g B3 conical just shipped.
I'll play around with the process bearing in mind all your suggestions. Next brew day, I'll snap a couple of pictures to illustrate the process and let you know the results.
