Ming the Merciless
There is no mercy

- Inside my skull
Re-fettled my earlier fettle - I'd swapped to a 28 toothed big cog on the cassette, from a 25 (makes all the difference up hills ), and increased the chain by a couple of links, but it was jumping and catching the derailleur, so back to the original length and it seems perfect, no slipping
Also refastened the gear cable, as I'd clamped it on the wrong side and reset the lower limit screw, as I didn't do that earlier either.
Did you adjust the b screw? Might be the missing tweak for the longer chain and bigger cog.
