TRACKER
Some like the thumb-hole some don't, personally I think they are nice on the target range and awkward to carry in the woods.
If you are watching your dollars close the Z5 Omega is on end of the year sale at Walmart if you get one use a inch pound torque screwdriver on the stock to barrel and action screws 28 inch pounds if you do not have access to a torque screw driver just remember NOT to over-tighten the screws the Tupperware stock won't take it. I have one I paid 150 dollars for at the end of the year sale 4 years a go it has not been modified except for putting a vent liner in the breach plug when it got flame cut, it still shoots a minute of angle with a half dozen different loads.
