I sent you my suggestions a few days ago.
As an out of state team, obviously the less school we miss the better. For the group of kids I brought, we left right after school on Wednesday, drove 8hrs to Ashland OR, stayed the night, then practiced and drove the rest of the way afterwards. We got home early Monday morning and some of the kids still had to drive another 4hrs to get home. Some kids had to miss Wed and Thursday to attend. Staying Sunday would've meant missing another day.
Then you have graduation, finals week, etc to deal with. I know several of our better kids couldn't attend because of this. However, unless its deep into the summer, you will always have this problem. The only solution I can think of would be doing it the 3rd week of June or the end of June, but then you're dealing with the elite wanting to attend Freestyle stuff or training for Nationals. Memorial Weekend, as much as I feel for Lawson's argument, may be the only weekend we can do it in order to benefit the group as a whole. I myself, am now coaching the Cadet team at Fargo and will be missing my anniversary, my sisters 30th b-day and my sister in laws wedding. Needless to say, it will take me a decade to make up for that.
IMO, stick with the duals and try and work in an extra dual or some all-star exhibition matches and definitely, showcase the finals match. I understand we are wanting to not be stuck in there all day Saturday, but even with 32 teams and the amount of mats you use, we are still in good shape. Our unofficial dual state tournament is ran over 2 days on 16 mats and features 76 HS teams in OR. Getting in one extra round won't hurt people IMO.
Elite and Varsity divisions would be okay I guess, but it just depends on what your goal is. If your goal is to give everyone a taste of top level wrestling, leave it the way it is. If your goal is to have everyone compete to their level of ability, separate them. All first team elite teams, would be in the elite division. Any 2nd team from out of state would be in the varsity division. Then divide up accordingly. If you can get 16 out of state teams and 16 varsity level teams, with some out of state teams mixed in, that would be awesome.
Also, I know your goal is to get the midwest and east coast teams to attend, and I'm also sure you tried to get more local states to attend as well. Let's figure out what needs to happen to get both. There is no reason why CO, WY, MT, NM or UT couldn't either combine to make some teams or just bring an in state team. If we can drive 16hrs to make it happen, they can too, as a minimal cost. We charged our kids $200 each and that covered a shirt, a singlet, hotel and gas(the biggest expense), as well as me buying a team meal on Saturday(man wrestlers can eat). Next year, I think we'll get away with charging $225 a kid and be able to do the exact same thing. For 6 matches, memories, the best singlets at the whole tournament, great food, a nice hotel and a decent drive home, you can't beat that.
You can have all the talent in the world, but if you're not willing to work hard, then what's the point.
