I've only been to one ML competitive shooting event and that was 11 years ago. I can't remember how the shoot was conducted in regards to flint VS percussion, etc., but I do remember there were several of both shooting various events, aggs, and so forth. I fired percussion only for every event because that is all I had. Now that I think about it, I don't recall anyone complaining they were outshot by the flinters, or percussions, or whatever else may have been out there.
If I ever get lucky enough to get to another match, I really don't care who shoots what (or what I shoot, for that matter) because at the end of it all you scored what you scored with whatever you decided to shoot with and that will be the end of it. The bottom line I guess is to enjoy whatever you are shooting.
What matters most to me is what I shoot when hunting. What determines what I shoot on a particular hunt will be based solely on wind and moisture. If I hunt close to where I live on the Gulf Coast, it will almost always be lots of moisture in the air even on a fairly bright day. If I hunt more away from the area I live in, the air will be different and as long as it's dry and the wind is down the flint of course is really no problem. The bottom line here is when hunting I'm going to use what is least likely to fail depending upon the weather conditions because I definitely want to bring the meat home.
As far as building goes, I really can't see the justification in building a percussion Brown Bess, or a wheel lock Hawken ... (
