Dale,
I like the sniper stock personally. I just recieved my .204 SPS Varmint this week. I am going to be sighting it in within the next two weeks.
I will have to see how well the factory stock works for me, but you have chosen a nice option for your stock I think either one will work for you, but I prefer the green sniper stock myself. That rifle will be a heavy one for sure.
