Thanks for the responses.
@ Yooper, I will go forward with my APA and use ~50% Vienna in place of a Pale Ale as I reconfigure my next batches.
@ humann brewing, good suggestion! I found that when searching, tempting along with going with the Vienna ESB. I kicked the idea around, but decided to just do the substitution above with a recipe I brewed before so I could do some comparing.
But that leaves enough grain to try a batch if the below turns out to be a bad idea.
As much as I would like to try to brew a Vienna lager, not set up for it. As you mentioned Amber I thought a Altbier may be suitable. I am going to dig around the interweb and check out some recipes. I would like to see what I can configure with the hops I have on hand.
