Sorry if this has been discussed at length but I can't find any comparisons between the MMR and FTB cooler kits, why the large price difference, and any other pluses and minuses, reliability, etc. Thanks for any inputs guys, new to this forum. FYI I track So Cal 7-10 times a year even in the hot summers, so this is a very needed upgrade. 2019 PP2 stock....for now.
