Thanks for the input everyone. I will be back to the shop and the range, but with altered expectations of how I should contribute to the business.
jhg (Joshua), I have a few comments about what you wrote:
1. "Its an issue of knowledge and skill. Not trust IMO."
I do believe it is a trust issue. If you present yourself as a professional in a particular sport and are willing to deal with novices who cannot judge your knowledge and skill fairly, you have the responsibility to do a professional job. If you cannot do a professional job, for whatever reason (time, lack of skills, etc...), it would be considerate to let the customer know this and suggest he do more research, or at least offer realistic expectations for the service you will be providing. (Equally, I have the responsibility to learn about the sport and make judgments for myself - a process that can be hastened with a trusting relationship with someone more knowledgeable than I - such as this shop keeper).
2. "And if you have to ask if its moral to use his range, but not support his business or help him become a better trad dealer, then maybe the issue you should be worried about is a little closer to home."
Whether it is right of me to use his range or not is not black and white to me. I pay fees to be on that range. Originally, I felt that because this man has helped establish a community that I can learn from and have fun with, I should be supporting him fully. After reading people's comments I feel better supporting him in the aspects of his business solely where I am happy with the service.
Additionally, I think seeking the experience and collective wisdom of a group, like Trad Gang, by asking probing questions about a moral/ethical dilemma is a great way anchor my own feelings. It provides me with greater insight and offers new solutions (like yours, see #4 below).
Finally, I should add that this shopkeeper is incredibly nice. I enjoyed talking with him and I got the impression he enjoyed sharing with me. I do not think he has tried to bamboozle me. I simply do not want to end up spending money on things I will not be happy with; and I tend to do this more when the salesperson is charismatic.
3. "Sorry to be so blunt, but good trad shops usually evolve. They are not instantly great."
This individual has been in business for around decades. He uses this fact to sell his services. As many people have correctly assumed, he mostly deals with compounds; He does not stock much traditional gear so you have to order it. If my patronage helps sway him towards stocking more traditional gear, I will try to support that effort when I can. To pay for things that do not suit me in hopes the shop will evolve towards a my traditional needs, seems unwise: It supports his current model.
4. "Talk to him one on one, in a way that shows you are interested in his shop, but want better knowledge coming from him. Do it in a way he won't feel cornered."
I agree with you on this point. Good idea, Thanks.
