To be fair, Kennedy is a broadcaster rather than a tipster - and I find him alright at that to be fair (although others seem to find a head melter).
I don't really come at it from a tipster element (as I'd never even consider following a tipster blindly), but people whose opinions I would take note of would be Gary O'Brien, Kevin Blake, Tom Segal, Jonathan Neesom, Freemantle, Steve Mellish etc.
Not sure if the latter three are on RUK a lot these days, but they have a savage amount of knowledge between them.
