I think 60x is perfect.... Too much and it is hard to keep a steady hand like bde0001 says.... Just don't get overzealous on the trics. I use to chop at cloudy trics and freak out the moment I saw amber trics - amber is suppose to indicate THC is degrading. But cloudy/clear is subjective as cloudy for some isn't cloudy to all - now you gotta worry about cloudy enoughWhy can't you use it on the plant? The only jeweler's loops I could find that were affordable had 30x max magnification. Just didn't seem like enough.
I find 15%-25% amber is good for me
