I, also felt much the same way as you...I looked around the rooms for a long time searching for that one special person who "had what I wanted"...
I finally asked her...I found that although she gave me a few tools and a couple of suggestions that most of the time we ended up talking about her issues instead of working the steps. She also borrowed money which was never repaid.
So I asked a second woman to be my other sponsor, and I do know that I could call either one of these ladies with multiple years if I had a program question.
Now, I never really "fired" my sponsors...
but I don't call them on a daily, weekly or even a monthly basis and to tell you the truth I can't say when the last time was that I saw either one of them.
However, most of the time I chose to use God as my sponsor...
I have difficulty in putting that much faith in a mere mortal.
I did however use the whole group, and took bits and pieces from everyone and atttended many, many meetings in the beginning.
So far, my program's been working for me...one day at a time for a few 24 hours now.
August 15th will be 5 years of sobriety from drugs and alcohol.
