Yep, I know the rule of thumb and i know it'd be on my head etc. I may give it a go or may splash out the extra, just seems a waste when the front has loads of life left.
Also how easy are they to change by myself? I see one of you guys did it on your xt-x which are tubeless obvously, I used to do my own on an old DT125LC I owned. And is it essential to have them profesionally balanced if I do fit them myself?
If i can do em myself I'll go for the pair probably, just im on a budget as not working at the mo as im in France learning the language for a while before starting work.

Cheers for the adivce
