If you're using a stock that has more of a rounded forend, I would definitely go with the RRS vyce. I've used both and they're both solid choices. What are you using for a tripod and mount? If it's in your budget, I would get the RRS ball mount to go along with the vyce. That would be the most solid option. The hog saddle is great, but often you are limited by the mount that connects it to the tripod. They can be pretty flimsy.
