A good repatoire against sicilian?
2 nc3, followed by either 3 f4 or 3 g3, as long as you put in some work to understand the ideas involved.
Something like this hee hee

The good approach in openings is to play with ideas, rather than memorization.
With this in mind, Closed sicilian and Grand prix attack are a very good ways to handle sicilian as white.
A pertinent repertoire is playing both, according the circumstances (in some black responses to 2.Nc3, it is better to continue with f4 or with g3...).
Smith Morra is great at club level. I find people are not well prepared under 2200, even than, I've beaten 2300's in classical games with it.
