Now that I have read the OP's responses, I would like to try and be a little more helpful. If he truly wants to go with Lat, then I want to give some info.
Here is what I would suggest to build the foundations of a Lat bag. I don't throw anything higher than a Speed 9, though, so take that for what it's worth.
-Opto Saint. Nice line-shaping ability with a hefty amount of fade still. Good glide.
-GL River. Can be turned over with some snap, and hyzer flipped for nice straight flights.
-GL xXx. Headwinds/utility
-Opto Pain. For that Roc-like flight, but in awesome plastic.
-Opto Fuse (heavy). Excellent for straight or turning shots.
-Opto Pure. Awesome for short drives and approaches.
-Pure or Mercy in your preference of plastic.
You may want another high speed disc like a Flow or Riot somewhere in there, but I haven't thrown those ones. With the ones I have listed above, you have distance, line-shaping, and windy days all covered. And the plastic is sexy as hell. I threw all Lat for a bit, then tossed the Roadrunner back in the mix (along with some MVP), but it is a great brand to build a bag around. Have fun!
