Ok, I think I should probably open this new thread with a clearer question and clearing up some things. I’m getting the same type of answers even though I’m asking different things. Maybe I haven’t worded what I want corrrectly hehe 1. I don’t want to spend more money than I already have. Please don’t suggest to buy this or that cause I won’t do it at this point and it doesn’t answer my question. 2. I don’t need to hear that I made a bad choice, or that I chose something that is too difficult for my skill level. I don’t believe in that. There’s nothing too difficult for me. I’m overweight, short, almost blind and weak and I hiked the Huayna Picchu mountain on my own. I can handle a dual RTA, trust me So having said that, how exactly do I know if I’ve already burnt the coils on my RTA? Before you ask, yes, I’ve cleaned the coils correctly. Dry burn, run a little water on them, dry burn again to get rid of water. What are the typical signs to watch out for when the coils are due for a change?
