I have had two TX200's, full size and HC. I have a tuned HW9K7, a Diana 54, a Beeman R7 ( a real sweetheart). An FWB 124D I bought in 1979. The newer FWB Sport rifle in .177. But the 97K and my HW98 are the most accurate. All of them are tuned, but the last mentioned are very accurate and so smooth.
