Chipy mate, I would go for it, as long as your family and little kitty supports you. You seem to have a great back up proffession, unlike alot of pilots. I would as Hap Hazard suggests talk to a few guys, and get their view, but dont get put off by the generic "Captain Sour Grapes" as he will tell your an idiot, because he thinks he made the wrong decision many years ago, get my drift.
When it gets down to it, if you really want to do it, JUST DO IT!
Good Luck in all your endeavours. By the way, I m still chasing Jet slot like most , but I havent managed to catch that final wave in either.
Regards
