Having taken DIR/F, and ushered many (MANY) of my friends into the class, I get this question a lot. In fact, I was just speaking with a buddy about this last night. I've given this some thought, but I haven't polished it yet... so bare with me as I try to memorialize this for the first time in writing.
SNIP
I'm sure there is more I'll come up with once I give this a little more thought. Have fun. I went into my DIR/F with 16 pound and though I was properly weighted. I came out diving 8. I went in doing 30 dives a year, I'm now doing over 200. It changed everything for me. Not just diving, but health & fitness as well.
Its the single best thing I ever did for my diving, taking DIR/F.
Come back and tell us all about it!
