I’d take the 350’s over Hope, more reliable and better freehub design, but stick the upgraded ratchets in if you get annoyed by slow pickup (some do some don’t)
I’d take 240’s over the CKs too (owned and worked on numerous examples of both), lighter, simpler, just as good performance wise and need less regular maintenance.
If only they did 240’s in pretty colours…
One alternative I’d looked at was the superstar switch ultra lite- only goes up as far as 15mm and weighs about the same as a 240, cheaper than the lot. SS front hubs have been fine for me in the past.
This is also not a bad idea for the front if you’re not bothered about non-matching hubs, there’s not much to go wrong in a front hub so any decent shell coupled with decent bearings will do fine, easy swap adaptors on the SS/Novatec options and very good value for money, even if the OEM bearings don’t last as long pop decent ones in later if needed
