I was a menthol smoker. Most of the menthol liquids I tried really took some getting used to. I ended up liking spearmint instead. Quickly, I moved on to sweeter flavors. I do like throat hit, but there are some really mild flavors out there. RARELY, do I use any menthol these days. It's great when I have a cold though!
I agree, try a higher VG ratio.
I got some Kringle's Curse peppermint, though I dislike menthol cigarettes intensely; the peppermint is just different enough, and yeah it will clear your sinuses beautifully -- it's also good after eating spicy, garlicky food, like pizza or spaghetti -- gets rid of that garlic breath/aftertaste! It'll also "clear your palate" from that dreaded "vapor tongue" when you can't taste your regular vape, so you can start to taste it again.
