ive used the Pat brand reels for ages and have found that moisture is the main problem espescially when loading in a changebag, hands moving within that closed space inevitabley causes moisture levels to rise and some emulsions gets sticky. I always run a small hairdyer on a warm low setting over the reels to eliminate any skerrik of moisture AND with super clean hands. . . have never had a problem. If you can eliminate the changebag all together and load on a bench in a darkroom its very troublefree.
