Ok...here's my take.
Bottom line: We all pour to catch more fish or help someone else catch more fish!!!!
All the other factors such as colors, glitter, more/less salt etc. hopefully end up at more fish!!
I don't think Chris (Al's worms) pours his weapon worms thinking about just making a buck or Jake (woodsac) designed his rocker just to have something to do with his time !!! They have the passion to catch more fish.
Look at BigZ and his molds or Javier (BASS8BAITS) and his infamous 4 color pours...plus new guys like Charlie (njfishrguy) and his sticks. I've received baits from swaps from guys (like Mojo and BigZ) that you just couldn't put a price tag on!!
All because we want to catch more fish or we want the guy/gal we send our baits to to succeed!!!
Check out some of the hard bait paint jobs and designs sometime from LaPala, cullin8s, B&B (I could go on for days with the awesome stuff all the hard bait, jig and spinner bait guys do!!!).
The passion to catch more fish is "injected" into our baits, one by one. I really don't think you can get that from a bait at your local sporting goods store!! (IMHO )
