Canon 60mm macro trick with the 7D

I think I finally learned how to use my 60mm macro. I guess it's not a trick, but I think it will help a lot. I LOVE my 60mm macro for macro (of course) and for portraits. It's my main portrait lens. But I have always been frustrated by the fact that it doesn't have a focus limiter. When I take a portrait it will often search for focus in the macro range. It takes 1-2 seconds to finally focus at portrait range. By then my subject (18 month old daughter) has moved on. I read somewhere that you should turn Custom Function III:4 to Focus search on so that it will always try to focus for you. But this is what is causing my problems. I tried turning it off and if the subject is not near the focus distance it won't even try focusing. But if you manually focus close to your subject, macro range or portrait range, it will autofocus it extremely quick after that. So if I shoot macro, swing the manual focus to macro range and vice versa. It never leaves the macro range to search longer range and it never leaves longer range to search macro. I need to practice this to get good at switching between them, but I think it will be a big help. Is this something that other people do as well?

To make a long story longer, I just ordered a 100L to go with my just ordered 5D classic, because I figure it will be close to my 60mm on the 5D and gives me a longer lens on the 7D. Do you think that the 100mm will make me want to sell the 60mm? It's size may sway me to keep the 60mm and sell the 100L.

The size of the 60mm is something I hated about that lens. The size for carrying was fine, but into macro and manual focusing I hated how small and close to the body the focus ring was.
The 100mm was a much better fit in use for me than the 60mm due to the physical design.

I use the manual focus ring on my 60mm and never have problems. I like how small this lens is. And also how sharp it is!
