Can a good hammer make one a better carpenter?

Can a good gun make someone a better cop?

Or it's like a chum of mine once said... We were sat, a bunch of us, around discussion different dart weights, different materials... different flight materials and textures and what worked better for some and not other...

"Bullsh!t!", my chum said... "You can either play darts or you can't."

And to make his point, he went off and grabbed a set of plastic darts (Like they give you to throw at the mid-way... all plastic except for the brass head and point on them) and proceded to beat all takers with them...
