Default RE: If I switch props will it slow me down on approach?

Soo, Iwas wondering if switching propellers was in order. I run a 10x6 now, if I went to say an 11x5 or 11x4 would this help? or am I just gonna have to learn to make my approaches from lower altitude so I can keep the speed down?
Sometimes using the same size prop but another manufacturer's brand will allow you to set the idle rpm lower. For instance an APC prop seems to be slightly more efficient than a MA prop at idle and usually the MA prop will idle a few hundred rpm slower. Less efficiency and a few hundred rpm will both help to slow the airplane down. Also doesn't cost much to experiment.
