Width Stereo Enhancer in a mono mix

[mojovoodoo]

I was wondering if anyone had some insight into this or similar stereo field plugins:
I was mixing and producing one of my tracks and noticing that some of my stereo tracks might not be true stereo, (the left wave file looked very similar to the right one) and was trying to add some fun and interesting depth to my mix, and decided to play around with the AIR technology width stereo plugin. The most I have played with any sort of stereo field plugin was the randomized panner,(mostly by Waves).
Anyway, the mix was starting to get really fun and the levels were solid and locked. BUT, once I switched into mixing in mono mode, the tracks with the width stereo immediately got lost in the mix (duh! It took me a minute to realize what was happening) I was going "WTF?" and turning up the track more and more. And then when I switched back to stereo, obviously, but unbeknownst to me, the track was way up in the mix and super hot.
For now, I am just going to leave it in stereo mix levels. But I realize the importance of always switching your mixes back and forth from stereo to mono and is how I have been mixing for years.
I'm wondering if anyone is well versed in this application and what is the norm for this instance of using stereo width enhancement? If the mono mix is just ignored and to just rely on my ears in stereo?


Also, the conundrum is that nowadays, unfortunately, people aren't listening to music in stereo that often. They're just listening to your mixes through some cheap spruced up transistor radio speaker on their phones, which any android phone I've owned, was always in mono. Even when I hooked it up to one of those small portable lightweight blue tooth speaker system, it actually was a mono speaker system. I had always thought that there was some cool advanced stereo speaker placement ergonomics in play. But I guess I assumed wrong.


Any thoughts on this whole issue? Thank you!!


Oh, and here's the mix I went with. The lead synth part is what I used the width stereo enhancer on:
