In my early club tournament days, I was loyal to one local tackle shop. I would recommend him to others and his prices were very fair. As I started to fish the tour, he set me up with a very big rod/reel company. I could give him what he wanted (my time) and he helped me out with a pro staff deal that, even though not cash, helped me out tremendously.
As I fished the Ontario tour, a few other mfgs approached me and offered goods but didn't ask for much in return. I appreciated this very much. I was told by a rep that if I ever needed support, just ask, from a major boat motor mfg but I had to kindly refuse. I couldn't give him the time that he deserved nor could I travel the distances req'd, and I told him that. Canada is big!
I guess that the point is you should build a rep and be prepared to pay (even time) for what you get. In the end, it's better to build bridges than burn them.
