RE: wood vs. synthetic
I think the weighted synthetic you are refering to is "composite", when the stock is solid, but made from a synthetic composite material, like alot of the Sako's. The T3 is a friggin awesome gun, it was just hard for me to get over the fact that it feels like a BB gun I had when I was a kid. With a synthetic stock a 300 win mag is going to feel like a 300 ultra mag with a wood stock. I'm old school, go wood.
Buy the one you like best, and you can always add to your collection for the changing weather. If weather and price is a factor go syntheic 30-06. There is not an animal in North America that a 30-06 cant drop. Plus it's cheap to shoot, plus it an over 100 year old bullet proven to work.
