RE: picked up a tc encore and omega today!
I shouldered the Z5 at Walmart. I though it was fine. One thing about cheeking for open sights, it really depends on where the rear sight is set. If the sight was set real low on the ramp, that may have been why it was so uncomfortable for you. Were I selling one without a scope attached, I would be sure to put the rear sight in a position that felt comfortable for me. Chances are, most would find the fit somewhat comfortable.
A rifle which comb is perfect for open sighting, is to low for a scope. Most designs compromise between the two so that neither scope user or open sight user find the comb drop unworkable.
I have to admit. My impression of the composite stock of the Z5 Omega was just like my Sidekick, soft pliable plastic with seemingly little "composite material" in it, and too light in its weight (for me). But that is my impression, many others I'm sure will disagree with me on that and I think every single Omega and Encore owner will disagree with the "junk" assessment you made.
I happen to think its the level of satisfaction that matters most. A person doesn't have to have the greatest, most expensive rifle. He just needs to have a healthy admiration of his rifle and in his own mind think "its great". Everyone is entitled to that satisfaction and it should not be denied or compromised by another's own personal opinion. I know you would agree with that.
