Avgass (aviation gas? - I burn quite a bit of that in my day-to-day hobby...but I digress...) - WELCOME!  Love it.  Love it!!!  #20 is sweet.  Suggestions for consideration (not all but as you see fit):  can the font square up, italicize (as you've done) but possibly be a little less "roundy" (word?)?  Can the motto typeface be less casual, sans serif, italicized, sweeping or otherwise high-tech?  Yes, simple is best.  But we will also have the opportunity to emblazon this same logo down the side of a 53' long, 8' high moving semi trailer so you do have some "room" to work with adding a few more elements.  Can the flag stylize a little more and take on more of the uniform elements?  There is the sweeping golden swoop that is segmented by vertical lines (rather see that done at a slant for movement) and a gloss golden triangle - see the file upload.  Trying to work on that theme from the moment the band's moving truck arrives with their gear to the moment they set foot on the field - there's the golden swoop/triangle thing.  Again, just suggestions - take it where you feel moved!  You rock.  - Rich
