what difference between .5ohm coil at 30W or 1.2ohm at lower watts?

[Hotwire]

Got CF4 and subtank nano.

I like it between 25 - 30 watts on the .5ohm coil. It says you can run this at 15-30 Watts though the guys in the shop said not to go below 30, I find 25 okay.

Question is - what differences should I notice when I use the 1.2ohm coil which it says you should run at lower wattage - between 12-25 Watts?

I will use it when the .5 runs out so interesting to know what to expect?

You will get less vapor. Maybe more flavor maybe not. You will use lots less juice. And your battery charge will last longer.
