I was not impressed with king front hub on a friends new bike… he had to file his front disk mount on a brand new Fox 36 fork so the disc rotor would clear it!!
Apparantly King front hubs(certainly the model he had) have a wider disc spacing…nasty!!
Hope would be my first choice. I understand there is nothing wrong with King rear hubs and in terms of pawl engagement Hadleigh (spelling?) hubs are great too. In my experience though Hopes are very good. If you want super heavy duty pawl engagement you can upgrade them to a stainless steel freewheel. I have done that on my FR/DH bikes. Lots of hubs now come with aluminium freewheels including Hope King etc to keep weight down. For maximum reliability if you are a real “masher” its worth getting the stainless one.
Oops you said for a Cotic Soul… sorry for going OT. For that I would keep a standard pro 2 with Aluminium freewheel to keep the weight down. I use the pro 2 aluminium freewheel version on my trail bike and its fine despite going through losts of wet winters.
