First, I want to greatly thank Sam and JJ for sharing info with a newbie.
Second ....
Wow ......... Monk ......... Thank you for your demeaning attitude. Maybe others would like to know some of the things I asked too ....... Now I understand why they haven't been asked.
I just noticed that there seemed to be different graver geometries that aren't listed in many places. I was just wondering what people used. I didn't know I was a question that was forbidden.
I'm part of a bunch of tackle making, fishing, Rod making, kayaking etc forums. I have the best of equipment in all of those areas and I have learned a lot and shared a lot on them. I guess I'm use to people welcoming newbies and openly and everyone willingly sharing their expertise with others. I know I learn a lot from everyone I meet both newbies and oldies.
I'm not use to being talked down to ......... My expertise is in senior technical design and management of large telecommunications and video communications systems and I would never talk down to someone that did not have my level of experience in that way.
Don't worry .......... I won't ask you to share so valuable expertise again.
I have to tell you that I got more than a few of emails from others that just lurk instead of contributing or asking questions because the high and mighty attitude of some the last time I had the audacity to ask for more in depth explanations. Maybe it's something you may want to think about ....... Or not.
Please forgive me for asking a question ......... I won't make that mistake again.
I will join the legions of lurkers and get my education from videos, books and personalized professional instruction.
Again .......... Many thanks to Sam and JJ.
my words weren't intended to be demeaning in any way. if you took them to be such, i cant say much about that. as far as not asking any more questions, well that's kind of self-defeating.
