I have been reading up a lot on all of these and I'm just getting confused about how one has a short/long/ or no ester at all and also how long its life is. From what I read I guess having no ester at all is better right? Also about its life, I was confused about that part, is it about the esters life and how long it last? Just need a little info so I can be I can have a better understanding.... :wg:
