Thing is, its all standard kit hung off a very generic (basic) frame, so it almost doesn’t matter what you go for. At that pricepoint they’ll all be much of a muchness.
If I were you though, I’d go for the higher spec model of the two, as it sounds like it already has better forks, right?
Forks ain’t cheap, and the £80 you’d save by going for the cheap model won’t get you very far towards an upgrade. If you’re taking it offroad at the weekends, you’d be better off spending that wee bit extra now, than a few hundred quid in 6 months time when you’ve trashed the original (basic) kit.
