It all depends on the vehicle and whether they're mirrored and balanced from side to side.
Some flames look hideous when slapped on and/or on the wrong car.
I pretty much like all styles, but am partial to certain styles.
I like the long narrow Chicago, the Watson Crab Crawl, Tru-fire and the Tribal, to name a few.
I've googled but could not find anywhere where someone has put together images and names of flame styles, can anyone shed some light on that.
