Ok. So I'm feeling like quiet the jack ... today. I purchased a Reo mini from the classifieds a few months ago, and I noticed that the firing pin didnt look like the ones on my grands. Where they are curled on the end that makes contact with the battery, mine had a sharp point. It was evident that it had been cut to be that way, and I didn't know if it would effect the performance of my mod or not. So finally, this past week, I ordered one from Rob along with some orings. I hated making an order that small because of shipping cost, but I really wanted to change it. So I go to change it out today, and found that the spring on my mini is silver. I can't believe I've not noticed this. Especially considering I change my battery like three times a day. My question is, what is the difference between the two springs(besides the obvious color difference)? On my mini I don't sub-ohm. My coil is usually 1ohm. Do I need to make another order, and get the gold spring?
