hw 90 gas ram pros cons ?

[Byronic]

I have 3 x HW90s.
One a .177, both others are .22.
All nearly 30 years old so Mk1s.
The .22s are smoother but still not quite in PH Dragon or Sharp Innova territory

But worlds ahead of my beloved on Airsporters Mk1 through to S Mk2 c.1985/6

Some of us love them - and hang on to the sweet shooting ones.
How many of the less enjoyable examples have been "tuned" or otherwise messed around with?
