I'd go for the Sumatra .25 carbine. Lots of power and accurate. I have the 2500 .25. The carbine is about 2 lbs lighter. My 2500 with scope is around 9.5 lbs. I don't have a problem with the weight but if you'll be going out on hunts the carbine will be easier to haul around. The tip is threaded for a moderator.
