Over the past couple months I've been able to score some kegs at my local scrap yard. I have two straight sided kegs in excellent condition and a bulge sided keg that has a few dings but is in pretty good shape. My question is, which vessel should I turn the bulge sided keg into? HLT, MT, or BK? I plan on building a single tier system, so I guess the MT would have some symetry with the straight sided kegs on either side, but I'm not sure which way to go. I want to plan this out because I'll be buying the parts in the next couple of days.
