These are more like cologne sprays. I would get that in a to-go and test out your sweet spots. I’d start with two since the to-go’s have less content per spray than the to-go’s.
To answer your question as well, unscented options are expensive and I wouldn’t recommend, Neroli is good as is and IMO don’t need a cover scent but could if you wanted to.
This is a basic guide for the products.
Also there is a link in there by Steve O, follow that sweet spot guide, it’s helped many many users there find the ideal amount to put on
Good luck,
