I use the 316l without any problems whatsoever and was tipped off on it by another member right here in the forums lol, at first I was skeptical but overall I am very happy with it and there are ALOT of places to get the 316l as opposed to the 317l (this is just IMO) and even online jewelry shops carry it, I just make sure I verify that it is surgical grade 316l and wash the strand I cut off with dawn and hot water (just in case, I hate the taste of machine oil and probably not good for you lol) the only problem is I can only seem to find it in 26ga, 24ga and then 20ga, 18ga and 16ga which irritates me because me go to is always 22ga but oh well, I have been making due with the 24ga just fine and rocking it at .13 currently
