I had a long-haired cat and really, shedding wasn't the problem. I actually found it easier as far as shedding goes, because they tend to shed in clumps that are easier to pick up than individual hairs.
On the other hand, the real challenge is matts. They tend to get them under their "armpit" area and on the backs of their hind legs. If you can find a way to brush those areas regularly, or even shave them, you can head off problems before they start. I wasn't so lucky . . . we had to have our cat sedated and shaved at the vet about once a year.
