Getting ready to go to a World Champs with the intent to do well involves a lot of time and energy. It is basically a second job. So I made the decision based on many factors that I wouldn't try out this go-around if I didn't have that extra time and energy to take it seriously. Career and family are first priorities and hobbies should be fun and rewarding, but not detracting from the first two. I also just moved 50 miles further from my practice field to have more time for my first priorities.
But as I said, I am in total support of anyone wanting to give it a try and maybe this is a good way to get some new faces here (US) in F5D.
