I've heard of them but we don't have trials around here. I guess some of it depends on how much you want to spread entries out over different venues and what venues are your priority.
I think it's fun to try different venues. If given the choice I'd go with CPE as Kiba is fairly close to her CATCH, but there are a few AKC, USDAA, and TDAA trials we'll be doing this year.
I saw a bunch of their courses maps including their Nationals. Looks easy even at the highest levels, so imo a good place to start a novice dog or handler.
