I have about that much distance, so I guess I'll chime in. In general, the candy plastics seem to be shorter and more overstable than their lower priced counterparts, so keep that in mind when choosing the discs and weights. You will be handycapping yourself to a point because of the lesser distance you can get with the candy discs, but if you gain confidence by using candy discs you may end up ahead.
I've found that, unfortunately, the hardest thing to find in champion/Z type plastic is a straight, control driver. I haven't tried a whole lot of them out, but I'd imagine discs like the Leopard, Cheetah, Gazelle, Sabre, Teebird TL, XL and XS (among others) would be good candidates. You'll probably have the best luck with a hyzer flip type line for any of these since they might be a little high speed understable and low speed overstable in champion type plastic.
Pure distance discs, like the Beast and Flash have worked well for me in high-end plastic, though. For me, the types of shots where I'd use these are the ones where I have the highest chance of hurting a disc and require less accuracy than a straight, control driver. The Flash has been noticibly more understable than the Beast, but also longer. I think the Beast has been more predictable, though.
I throw a candy Gremlin for my midrange shots and while it may be a bit overstable while new, it gets to be a very straight midrange that handles a headwind well. I believe that there are less overstable candy midrange discs on the market (that are in production, too) that should fit about slot in stability. The Wasp, Buzzz and Breeze come to mind from Discraft. The Spider, Cobra and Panther seem to be decent midrange discs from Innova that come in candy plastic, too. I've been experimenting with the Millennium Aurora MS and have a QMS version as well. I'm finding that I'm having some trouble getting a good release (deficiency in my technique), but when I do get a good throw they go very straight.
Personally, I don't like candy discs for putting. I don't like the way they feel for putting and it seems to me that they hyzer off too much for my tastes. I have friends who love them for putting, too, so it's really up to the player. However, for short drives or long upshots a lot can be said for candy discs. The added overstability can make it easier to get a gradual left turn and they can work well in the wind.
For overstable drivers, I think candy plastic discs work great. They tend to take extra abuse because of the way they land and extra abuse can cause them to be less overstable wich can defeat the purpose of the disc. I'll defanitely admit that an overstable driver broken in to the point where it is stable can be a nice thing to have, though.
I've found that I have the best luck with discs I'm the most familiar with, so if you can get familiar with a bag full of cany discs, you'll probably find success. It's probably a worth while experiment (if you have the money) to try an all candy bag just to see what it's like, but I wouldn't rule out other types of plastic forever. I know on a more open course I'd much rather have a bag of low level plastic even though I normally carry some candy discs. However, on a wooded course I'm much more comfortable throwing discs I'm not worried about damaging.
