@Oginme @McKnuckle
I basically agree with everything you said, thanks for feedback.
However, I was hoping someone with a 6.5 could confirm my dimensions so I could back a decision based on data.
I've been contemplating the 6.5 as a mash tun for 5gal batches. Can someone with the 6.5 confirm my estimated dimensions and thinking? (see image below)
My reason is that I do all of my 5 gal all grain batches (typically around 10lb grain) in a 6 gal cooler at 1.3 ratio mash with plenty of room...
