I hear ya, I catch myself sometimes wanting to offer advice/knowledge to those who don't want it. I now really only try to offer an opinion or advice when asked, or when discussing a topic and maybe offer another a suggestion or somethign to think of or consider, certainly not force it downt heir throats. Maybe this is a bit different from what you were referring to, I enjoy bowhunting and shooting, I think its just my nature to not only want to improve myself, but others too, but I have since realized that some guys are happy if their bow shoots ok/well and gets the job done, and I understand that, even myself, for instance I haven't gone to a drop away rest, I feel they're probably the best style on the market, but my current rest has me shooting great, so why change anythign I say.

though I think I would rather have guys around me that offered advice too often than those guys who won't let any secrets get out......ie if you see a monster buck, tell me, I want you to shoot it just as much as I want to shoot it.
