I have been into Encores since their inception. I have use several mounts over the years, but prefer the MGM steel base. I use either Warne or Burris XTR rings.
I have the twist in ring mounts on the lesser kickers. Only issue with the short setup like the TC duomount, is such a short clamping area on a long rifle scope, but they work great.
The one piece style like Talley and Dead Nutz work good too, but I have had heavy scopes slip, even after lapping.
I had my buddy put a brake on my 460, but it didnt help much. Then had it ported behind the threads, and it was better. So I had him make a thread protector or collar over yhe threads, same diameter as barrel. Then drill thru that for more porting holes. It has lessened the muzzle rise to almost nothing now.
