Marco,
Not sure how to answer your question because I am not real sure what "all in" means.
I love fishing for any species and do all my fishing with flies I tie and a fly rod.
The only club/group I am a member of is a local fly fishing club here made up of a group of people who love to fly fish.
I am a volunteer for Partners With Healing and assist with teaching fly tying and fly fishing to disabled vets.
I am a volunteer for teaching fly tying and fly fishing to the "boys" at Arrowhead Ranch.
I teach fly tying at the local fly shop on an "as needed" call.
If the above means I am "all in", then I am 100% "all in".

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
