How about awarding Worlds qualifier points at for placing in say top 5 at 'major' shoots (list of shoots to be published before the season starts). Divide up the points by the number of shoots attended (minimum of 5 shoots attended required) and hey presto you've got a list of the best, most consistent shooters in the land. All EFTA have to do then is work their way down the list at the end of the season inviting people to go to the Worlds the next year, until the team places are all filled. Add in a deposit to confirm interest if you like. With a ready-made reserve list and it's job done.
Still too late for Germany though, so we'll just have to settle on a system in place next year for 2014 and do the one-off qualifying shoot for thang for 2013. Just let me know when and I'll start washing pellets!
