HiTech is as fallible as anyone.
Again, it used to be one, late-war arena that would promptly close and open two more at the strike of 5PM. The one main had room for 600 sticks and would frequently have 400-500. When it closed at the magic strike and open to two, 100-150 would leave altogether. It took AH forever to figure out it was impacting the game. Maybe years past having this change from one to two worked, but life and business is dynamic. Things change. And if you don't change with it you are on a path to death.
I like the idea of doing a two-country setup in the MA on Tuesday nights for a period of time. Let it go on for 5 hours over 6-weeks and see what happens. One thing for certain, our numbers are slowly declining and in part this is due to the lack of fights. Increase fights, fewer will leave and if it works well, more will return.
Times change, get with the times or go home....old business saying.
