The River wouldn't turn over all the way too often, only on an ugly release. The Maul was turning hard at release and would usually turn into a roller around 200' for a 300' or so roller. I've never practiced throwing rollers so I don't have the aim or know the angle to hit to take advantage of that shot. Might be a good disc for me to bag that way, but I just passed it to a buddy.
The Renegade was the same story, slightly less US and would usually just ride an anhyzer line to the ground. However, I've had it roll a few times when I bagged it consistently. Normally, on a slight hyzer line, the Renegade would flip flat and sail for about 350' and fade back. Not a bad disc by any means, just didn't fit with me.
Last summer I went on a Trilogy kick, got a couple Swords, a King, a Sorcerer, a Bolt, and a Saint. The Saint worked well, but all the drivers were massively understable. The Sorcerer just burned over right, the Swords were quite understable, but controllable and had amazing glide, the King would always come back with a decent fade, but not before flexing out of a HUGE right turn, and the Bolt was just a L64 King in my mind. Not quite as far right, but not the flights I prefer.
