If you have the kit lens, and you don't like the hood, don't use a hood. The kit lens has a hood that's made to be used for 18mm on EF-S lenses for 58mm filter threads.
For the larger 77mm threads, there are alternatives. I bought my 17-40L which came with the 17mm petal hood for fullframe lenses which didn't work well on my 1.6crop. So I bought the efs17-55 hood and it works well now.
