Mmm interesting post this, I shall be interested in the replies. I have an article on fly fishing for chub in front of me now (FF & F Sept 2009). If you don't have a copy you can have this one.
The man fishing recommends a Rubber Legged Stimulator. Bit of a monster, floating, with four great big legs. Not unlike I'd guess the fly mentioned above by muddler9. Big bushy and leggy seems to be the order of the day.
There's another interesting article FF & F jan 2010, roving for Roach. Hares ear, ptn and variations of are this ones prefered choice.
Me? Oh I'd just give them a Black Pennell, solves all
