I really like Hero.
I have three super sonics (taffy) for Recon and LOVE THEM. Very easy to float, somewhat puncture resistant (though Recon has a soft mouth it's getting harder), pretty consistent and easy to get out there. You need to have a fast dog for them.
I like the super heros decently, but I believe they are only candy, and I have heard that the taffy is most bite resistant. So the alternative would be the super aero, which I do not think I've thrown for my own dogs. Patton punctured his super heros the first session- they will probably last a month for me.
Jawz discs are FANTASTIC and while I only have one, it is the only disc I've used with Patton that doesn't get punctured. And he's used it for many months, taco'd it, etc.
Airs and super heros, and CS hyperflite discs are nice standard discs for dogs that don't have too hard of a mouth and don't taco discs. Super hero being the most durable, but IME, not worth it.
I second the blems- such a great way to get cheap discs, and combine orders with friends to get cheaper shipping. I just ordered the bag bundle where you can pick two styles of discs and their quantities (as blems) and they are cheaper than regular blems, and come with a disc bag. I ordered 12 discs I think, and the difference in price basically made the bag free.
