Have you ever shot an HW98, 97k, 77k, a TX200 or a Walther LGU/LGV in 177.
If not try to find somebody who will let you shoot one.
If you are strong enough to deal with the weight of them, I think you will be pleasantly surprised. The HW98 is very good in .177 but very front heavy too.
Personally I've reached that stage in life where I prefer a lighter springer in 22.
You missed the cream of the crop, the AA Prosport
You can spend thousands and still miss a barn door or spend just enough and enjoy yourself. If you haven't got the talent to start with a million pound won't fix it. Whippet, Russell, a few bang sticks and a flat cap. http://www.smart-tech1st.co.uk
