The way I look at guides at this point in my life is that I hire them to learn from them. If they do not want to share thier knowledge then I will find a guide who will. It is just like going to training for computers, management or anything else. I am paying for further enhancement of my skills. I could care less if we hookup fish or not, what I want to learn is a new river or technique and what I learn on the water that day will make me a better fisherman down the road. All I have to say about passin' off a rod is that it happens, not only with guide, but with buds who fish together all the time.
Good luck and tight lines, Jeff
