A lot depends on the juice you're using, some flavours need slightly higher voltage than others to get the best taste. Also the PG/VG mix can make a difference too.
Having said that, when I mix a new juice, I generally start at 3.8 volts, take a few hits and gradually up the voltage to get my sweet spot (for me it's between 4.0 and 5.0 volts mostly).
With a 3.5 ohm coil you should be fine starting slightly higher than 3.8 volts though, from what I've read on here. But that's just my

i'm sorry, but you've lost me. I will have variable voltage, so unsure of the voltage to select. Is there an optimum current or wattage to achieve
Forgot to add, there's a chart on here somewhere of "volts compared to ohms". Maybe try a search for that 
Optimum voltage is subjective. Like trouble 1000 said, start low and adjust it up to the voltage you enjoy most.

im mixing 18mg/ml at 70/30. I appreciate there will be an element of trial and error, but wondered if there was some kind of guideline

thanks for that, I will do. I know ohms law well, but its awkward to apply when there are many variables
I've just found a chart that I had with an old ego battery.
They recommend 4.0 - 4.5 volts with a 3.5 ohm coil, but to be honest you can go higher without to many issues, most manufacturers air on the side of caution.
I'd suggest, start at 4.0 or 4.2 volts and work up from there.

3.5 is a quite high resistance, you should be able to crank the voltage up. I have 2.1 ohm stuff and usually run around 4.3 volts. there's a chart somewhere, or go to ohmslawcalculator.com and stay within 7-10 watts

If you're getting the vamo then set it for wattage as opposed to voltage (press both + and - at the same time for about 5 seconds to change from volts/watts and vice versa). Watts are a better indicator of vapor density and TH. Start with about 5 watts and go up. I wouldn't go above 8 watts or you may fry the coil.
thanks for all the replies, they're greatly appreciated. Using my current iclear 16's at 2.4ohm on an eGo battery (giving out a measured 3.9volts) is about 6.4 watts. but to achieve this with 3.5ohm heads, is about 8.5volts. the vamo is limited to 6volt, ...... I must be going wrong somewhere
3.5ohm I would generally go with 4.5v+ for my personal vape.
I generally use 2.4ohm at 4.1 volts
To each their own though! Just start as low as you can go and just take decent drags and in between each drag just knock it up one until you find the perfect voltage for you!

That's the best thing about the Vamo- you can run it in VW (not VV) and no matter what ohms device you put on it will always fire at the set wattage. Here's a calculator- just enter ohms and volts and it'll give you the wattage.
Watts - volts - amps - ohms conversion calculator
So setting the Vamo @ 6.4 watts with 3.5 ohms will give you 4.73 volts. I generally use anywhere from 8- 9 watts BUT I like a warm vape.
I'd suggest you set the Vamo to wattage and start at 5 watts and work your way up until you find your "sweet spot". Once you find the wattage you need not adjust every time you attach a new ohms device to it. Understand the advertised ohms is rarely the same as the actual ohms- use the Vamo ohms tool to find the actual ohms. Realize also diff juices taste better at diff voltages.
Best of Luck.

I prefer this calc mainly cuz of the formula wheel: Voltage current resistance and electric power general basic formulas
