The deal with La Rue is: "Buy Once ... Cry Once."
Not necessarily... since I bought my first set of QD mounts from LaRue, I've bought 6-7 more sets for the rest of my AR's. I've got more free caps and "beverage entry" tools from LaRue Tactical than I can ever use.
But back to the OP, I don't know of any advantage of Talley fixed mounts over QD mounts, but the advantages of having 2 scopes in QD rings for one African rifle are obvious. I took two scopes for my .375 on safari, a 1-4X Trijicon that I used to take my buff, kudu, and zebra in the brush, and then I switched over to a 2.5-8X Nikon for the more open country hunting eland.
While I was in training for my safari, I swapped out scopes at each range session, so I was intimately familiar with the mount/dismount process and shooting with both scopes as well as irons became purely instinctive. They
always returned exactly to zero.
