If you think that we're bad....try being a musician and debating your equipment.
Mouthpieces, reeds, ligatures, silver plate/lacquer coat, oil, large bore/small bore:banghead:
I'll take the same position on the polymer/metal debate as I do with my music rigs........use what works best for YOU. We are an incredibly complex machine ourselves, and to think that what works for someone else will inherently work for us is foolish.
Someone once told me that in an average marching band show, there is a possibility of something like 2 million mistakes that can be made...making it all the more impressive when a show looks good.
Look at all of the things that can vary between shooters.....height, arm length, palm size, finger length, finger thickness, near sighted/far sighted, neck length, upper body strength, stance.....well, you get the idea.
If you take into consideration all of those variables, it's a miracle that we can shoot each other's guns at all.
