My spring sag I think was just from the spring breaking in a little. I never run under .6 ohms on the Phid. Also I stopped doing dry burns on it as well because that could have been a contributing factor.
I had a spring collape dry burning on a different mod, now I use my Regulated mod for that purpose.
I'm just shooting for a warm, dense vape with a fairly quick coil heat-up. I just tried the doge (which is not suited for that at all) since it was the only one I had laying around not being used. I'm going to try a higher build on my Odin bf and see if I can find the sweet spot. I know my spring sag came from waaaaayyy too low ohms, and that is totally my fault. I'd love to replace the spring on my own if possible. It's not Fono's problem that I decided to push the envelope
If you're using Synthetic flavored juices, contact coils of.9-1.2 ohms, with an inner diameter of ~1.6mm, will concentrate the heat & give you a warmer vapor. If you vape Naturally Extracted Tobacco/ NET juices, the coil will gunk ~4-7mls, depending on the juice, and will need to be dry burned more frequently.
The density of your vapor can be increased by using a higher VG juice.
