If you like it and you can afford it. Go for it.
I have the Rallye 4 suit which I have owned for years. It is a great suit with loads of protection it just isn't great in the rain as the waterproof liner fits on the inside making the suit a bit of a heavy sponge when wet. I believe the newer suits have addressed this by giving you the option of putting the waterproof liner on the outside.
I have my Rallye suit for the hot days, An Enduroguard suit for wet cooler days and a Tourshell suit for commuting, erm and a BMW Coverall suit.
Damn I have too many suits.......
