Hi
@GolanT and welcome to the planet.
ive not got the kits you mentioned so can you confirm these are them as the solo plus is a sub ohm kit for higher wattage
https://www.vapeclub.co.uk/vape-kits/vaporesso/sky-solo-plus
same with the geekvape s100
https://www.vapeclub.co.uk/vape-kits/geekvape/geekvape-s100-aegis-solo-2-vape-kit its for sub ohm at higher wattage.
also youve not mention which tank you are using on this mod as it doesnt look like they come with 1.3ohm coils which youve mentioned you are using.
it doesnt matter what mod (battery) you use as long as you keep the wattage low and use a mouth to lung tank.
using a high powered sub ohm kit is the best of both worlds as you can start of with mouth to lung MTL tank just like smoking and then later down the road use a sub ohm tank on the same mod for higher wattage cloud chucking.
as said, youve not mentioned any wattage you are running at.
you have mentioned metallic taste though so this question has to be asked as so many people have made this mistake in the past.
have you got the mod set to wattage/power mode and not TC temperature control mode as TC can only use certain coils that have Ni nickel, Ti titanium and SS stanless steel coils.
i remember back in the day quite a few mentioned a metalic taste and they were using TC by accident.
if you could post a picture of your screen we can clear this up. you may need a couple more posts though before you can post a pic so in the mean time does your screen show numbers like 10W or does it show 220C or 100F (i dont do TC so these are just example numbers).
also the only backy infused flavours ive used are from Manabush which are worth a look
