I have the Wyoming Arms riser and am happy with it. A riser / ring setup is heavier than some single piece mounts, but the WA riser is built like a tank.
It's also less expensive if you're switching different glass on the same rifle. A few years ago I used the same gun to shoot a sniper match one morning and then carbine and 3Gun matches that afternoon and next day, by switching between a 3-9 and a 1-6 on the same gun. All I needed was a set of rings rather than an entire QD mount for the second scope.
