I am in a similar position, although I have only been spinning plates for 3 months. I have two young boys though as well, so I really have limited time to keep it going. I currently have 5 different women I am talking to, but really have time for 1-2 max...
My main plate goes against everything here... single mom, two kids, and she is 41 (I am 34). She is an HB7. However, she has to be the most giving person I have ever met. She makes me lunch the next day when I stay the night, brings me little gifts frequently, the sex is amazing (and she is completely open to everything), she has low mileage, has her own house, makes more money than me, interest is sky high, compliments, etc. and I generally just have a really good time with her. Definitely has LTR potential if not for a couple things (male friends, gets a bit too flirty when she drinks)
My thought is stop using OLD, just meet women casually, and when my main is tired of the fvcking or begins to show her true colors, I will have women on standby until I can find another steady plate. Starting over frequently is exhausting and really time consuming. I only have maybe 1-2 nights a week.
She is a cutie, but I wouldn't consider her hot. She has sex appeal, but not the tight body of a 22-year old. She has kids, but also doesn't party every weekend. She is older, but makes good money and owns a place in a good neighborhood in the Bay Area (not easy to do). I would consider her a quality woman, maybe not by SS standards of "hot" and "young" and "no kids", but none of the other 14 women I have dated in the last couple months even come close
One quality plate with occasional short term plates seems like a good fit for me
