the hw99s + 3-9x40 combo did me very well as a hunting set up a few years ago. very nice little rifles.
as for the hw98, well its the adjustability that did it for me. I love mine to bits, it feels so perfect as its set up to my shoulder and my eye/head 100%
I didn't get on with my hw95k unfortunately, it was a lovely gun, but just didn't 'fit' me properly, like the 98 does!
but as for the theoben..
if that's what you really want then go for it!!
