Well got my crafty cu's now to moding, think Im gonna use the rotarty tool. Interestingly after weeks of use my original cu show zero signs of deforming or cracking. I ususally run around 375 fot 2 min. Still gonna swirch over to the crafty top, mainly so I can use the water adapters availible.
Im already eyeing the crafty mod as my go to solution. That said I have hardly used mine and as of yet no problems but melting plastic has me leaning to the mod.
