Best compromise spring gun is the hw50s in .177 IMHO, especially if you are carrying it around a lot. A sling makes that even easier. The bigger guns like the R1, hw97k, D54, D350 get heavy real fast.
The HW50 is the shining star. Everybody loves them. Does so many things well. I have an R8 and would consider a new HW50(99) except IMO the stock is ugly.
Just got a HW50 maybe 10 rounds through it, so can’t say. Most my guns are heavier, I like the 85 and I’ve carried my 98 which would be my choice. Awesome for plinking. Crow
