#108 is unique but we like the script/handwriting options we've been getting.
#157 is our favorite - the red pops better the the grey in #156. The tagline gets a little lost so you might try giving it a heavier font, all caps or small caps to bring it out.
#215 is the best of the revisions because of the bolder font - keep working that way. The tagline reversed out of the bar is fine and probably helps, but the tagline font still needs more weight.
