I agree! In fact go for the 100 foot roll. When I do 5 gallon batches and use my wimpy 25 foot immersion chiller the water isn't very warm coming out and that's with me stirring the wort the whole time. Takes 20-35 min depending on what time of year it is. Bigger is better! You Won't regret making one a little too big but you will KICK yourself after you find you could of had one that would have met your needs better but you cheaped out!(hehe, I have done this! Don't make the same mistakes other people have. Instead learn from them.) And whatever you decide, GRATS on your up-coming chiller!!!!!!!!
