For those with the Spike CF 10 conical and the TC-100 temp control rig, any feedback on brewing 5 gal batches? I'm thinking about buying a conical and while my target batch size is 5 gal, the CF 10 is just a few dollars more than the CF 5 and would give me added capacity for those times I like to up the batch size. However, it the CF 10 really doesn't do a great job with the smaller batches, the added capacity wouldn't be worth it to me. Any input would be greatly appreciated.
