If top tube length fits you, all is good.
But try a smaller frame if you can and see if you like it. Especially if you intend off-roading!
That bike looks sweet by the way :)

Yes, it's a 92 Rockhopper. Bought it 2013 from another mtb-retro-freak and was riding it all winter 13/14 here in Berlin. Then I stripped, cleaned, and rebuilt it and now I only take it out for sunny sunday rides 8)
