Do it if you really want to. First ask yourself if you are going to have any regrets down the road if you don't do it.
This is what I did as I was in a similar situation. I "retired" from GA 4 yrs ago due to family reasons coupled with a dikhead boss I had at the time. Had about half the hours you have. Got myself a desk job and made good $$$, great conditions and perks.
However I kept thinking of those blue skies so decided to break out of the comfort zone and go back into GA 5 months ago. First job getting back into GA was on a Navajo! Now, I am heading into my next job with an RPT mob up north in 2 weeks flying twins with view to moving onto twin turbines.
Excellent conditions too I might add
IMHO NOW is the best time to get back into it if you are fair dinkum about doing it and are ABLE to do it taking into consideration finances,lifestyle etc etc.
Best of luck either way you go
