With their pace and ability to beat a man, I'd put Suarez/Bellamy down to beat Komps/Lescott 9 times out of 10.
Thing is Suarez isn't actually that quick, I was watching him the other day against Chelsea and there was one time he was ahead of the defender and yet still got caught. He has good dribbling ability and movement but in a pure foot race I'd say he is distinctly ordinary. As you say though, feed it into feet with Bellamy alongside and he could cause trouble, just don't expect him to be able to make the most of balls over the top (compared to say someone like Darren Bent).
