Yeah trey, that's correct.
I am running the Magura Pro XC wheels with my Magura Marta SL's and I am very happy with them. They are Hugi 240 disc hubs with 317 rims. You could check those out too.
All of your choices look great. However, between the frames I would have to lean towards the Giant. Everyone I have talked to with that bike loves it.
Just my 1 1/2 pennies.
