That should be no problem! I've seen all kinds of people convince themselves that certain things help regardless of whether or not they actually do!

Based on everything I've read, and my own tests, I'd say: don't lose sleep over VG's - at least not airtabs style. I'm open to the possibility that the delta style may be better.

A lip spoiler on the other hand is probably something that you could detect in your own A-B-A testing.
