Ultimately it's whatever floats your boat Arthur: personally I'd plonk for the 77 (no surprise there).
One thing that might be worth considering, for the sake of variety, is a selection of different stocks. I have 4 for my 77's. The original mk1, a 97, a cs800 and the current mk3. If for any reason you feel things going a little 'stale' then simply swap the stock and enjoy a 'new' gun all over again. It works for me.
I'm itching for a HW98 but the 'instruction manual' on the action is my reason for saying NO to a brand new one. Come on Mr W screw the nut, get rid of the writing - it's a tacky unnecessary addition that spoils the looks of the range. Go back to the smooth classy lines of earlier days and I'll buy one straight away.
