You could certainly go that route. However, I prefer a twist-top cap for my bases, when measuring by weight. The twist top (I feel) gives me greater control over dispensing. By only partially opening the cap, I can restrict flow, and give myself a slower, more controlled pour.
When you get your bottles (whichever ones you choose), and before you fill them with your real ingredients, I would strongly encourage you to practice pouring/weighing with water. Water will be thinner than your other ingredients, and therefore, more difficult to pour/control. When you can control/stop a pour (using water) on specific targeted weights, you are ready to start using real ingredients.
These are the bottles I use:

Something to think about when choosing sizes:
The weight/volume of the ingredient affects the pouring speed. A full/nearly full
large bottle is going to want to pour faster, than a smaller bottle, or a nearly empty bottle. Just because, the weight of all the extra liquid is trying to push its way out, when the bottle is inverted.
I have found a couple of ways to help control this:
-- Smaller bottles naturally have less liquid force/pressure, to compensate for. Consider using a smaller bottle and re-fill more frequently. It is all about finding a balance between convenience and control.
And, in the case of nicotine-containing ingredients (nicotine concentrate, or diluted nicotine base), remember to consider: the possible effect of oxidation, caused by long exposure to excessive headspace/air.
For my usage; I find a 2-4oz. bottle gives me a 3-ish month quantity... enough to not have to refill every mixing session, but not so much that the nic oxidation hurts the quality of my recipes.
Because PG, and VG, are much less affected by air exposure; I find 8-16oz bottles are fine.
-- Only open the twist cap a small amount. Open just enough to allow the liquid to come out... slowly. The thicker/more viscous the liquid, the more open the tip can be.
-- Tilt the bottle slowly. By tilting the bottle,
only enough to let the liquid reach the tip of the bottle, you can minimize the pressure the liquid exerts on itself.
-- Use the back pressure/vacuum/suction, that naturally occurs when pouring, to work in your favor. When you squeeze out a liquid, and then stop squeezing; the plastic wants to return to its original shape, and suck air into the bottle (stopping the flow of liquid). By first squeezing a bit of air out of the bottle (while still upright), and
then beginning to pour; you can use the squeeze-release/suctioning action, to give yourself greater control.
