Kind of strange I was just thinking about this last weekend after shooting the ORSAAP match. I've been shooting USPSA for about 18 years off and on. I don't think too much about the match being too difficult but it must be FUN. I shot in a squad of mostly older guys, myself included. We had some good stages that were a challenge. The only issue was way too much steel. I think we had steel on every stage. This is purely personal opinion and not being critical.
I bring this up only because after shooting with new shooters and less experienced shooters I saw a lot of faces that we're not having much fun blazing away at the steel. I know, I know you have to shoot everything to get better but it has to be fun. The only way to increase attendance with new shooters is for them to be challenged but not beaten down.
Again this is personal preference but a good stage breakdown for a local match should be a balance of a variety. For example:
1 classifier
3 run and gun paper stages, these are fun for every level of shooter
2 stages with a mix of paper, poppers, and steel.
In my experience if a shooter has 3 stages that are fun whether they shoot good or bad they will be back for more. If a club is to grow it is imperative that new shooters return and become regulars.
