Thinking about switching from 21 to 30

I have a chance to pick up an almost new Toro 30" Turfmaster at a fair price. I'm thinking I might just use it in place of my 21. I love my 21 but if I can cut 9 more inches per pass and still have maneuverability it seems like the way to go. I don't expect it to be as maneuverable as my 30" timemaster was but it should be close. The timemaster was pretty much as easy to use as a 21 or 22. I've got some yards that are too much for the 21 but not quite enough for the ZTR.
