Thanks for your detailed reply (and actually to everyone who's replied so far, thank you so much, I have carefully read each post and I really appreciate all of your thoughts). I am based in MK at the moment and think there's a club up by the M1, but I do need to double check. I think I will likely start with BSAC just because I'd quite like the weekly activity and community of it. It's been a long while since I've had the routine of knowing one night a week I'm out doing a hobby and I miss it (Will also be picking up rock climbing again as I really miss that!) Also, it's a lower cost upfront and as there's been a huge amount of change in my (and Jays) life recently, we have other upcoming costs which will take priority! However, once I feel comfortable enough, and once I think we're likely to do a holiday outside of the UK, I will definitely do a PADI course too, if nothing else than to add a bit of diversity to my training. Much like with Fireworks, I really enjoy the chance to work with as many different teams as I can as I ALWAYS learn something new from them; I never want to get comfortable in hobbies which have a level of risk.
