I believe the only way to find out if you'd prefer a different resistance head is to try both a 1.8ohm and a 2.8ohm.
to find out. If your on a standard 3.7volt battery the 1.8ohm will produce a hotter vape and more vapour with a shorter pull.
And the 2.8ohm head should produce a cooler vape but will require a longer pull to produce the vapour you are now getting with the 2.4ohm head.
My favs. are the 2.8ohm heads but that's 'cause I use 'em on vv and vw
devices mostly.
They work well for me at around the 4volt mark though, not much higher than the regular
3.7 volt battery produces.
At 2 bucks each it may be worth trying each, but you may just find in the end that 2.4ohm is your sweet spot
resistance anyhoo.
