So for those that purchased a 15 gal BK/MLT/HLT AG setup to be able to do both 5 and 10 gal batches, was it worth it? IOW are you finding that you do enough 10 gal batches to warrant the 15 gal tank size? Cost really isn't an issue for me per se, but I also believe in selecting the right tool for the job and don't want to buy a sledge hammer to drive a tack. Being honest I can't see brewing 10 gal batches that often, but I also realize that simply having the available capacity could change that -- decisions, decisions. :smack:
