Hi,
First of all, I fully understand if it isn't allowed, but with the recent and future competitions where your league matters I thought it was worth to ask.
Last summer I made two submissions with chilled water which put me in the apprentice league. Since then I have only used AIOs and air coolers, and have no plans on changing that, making me feel like I belong in the enthusiast league rather than apprentice. These are the two subs I made: GB3 multi and GB3 single. Feel free to delete them or disable points.
Thanks in advance
