All of these molds are available in DX in more weights than what are in the starter pack. I'm not sure what you're hoping to gain by picking different molds, but there's a reason these discs are in the starter pack.
In my experience most new players are confused with more than a couple discs. I get a lot of "is this a midrange shot because we're not on the tee anymore?" and "when do I use my putter?" I've found, for me, the best way to get a new person into the game is to keep them in the fairway. Once they have to scramble out of the woods, the fun is lost. The disc mold they're throwing is only important to me, the disc nerd.
Good luck with the group! It's a lot of fun to introduce new players to the game.
I am not questioning the validity of the discs included in the Innova Starter packs; just expressing my surprise that the price on them seems to be higher than the same three individual discs sold separately.
It is my intention that each player will have just one disc. But, that they can have some relatively small set of choices. The players will have the opportunity to play catch for a bit before the round, so they can get a feel for them. The discs are all going to be about the same performance-wise. But, I would like the players to have some variety of disc shapes since we all prefer different feels.
