Thanks. This helped, I decided to go with the LX 719 combo on my own. I have XT hubs from original build (m770s) that never gave me an issue, other than the free body a few times. I had to have that replaced last summer.
Now I have excellent XT hubs I can take time and lace new rims too and sell myself! Or just sell the hubs to cover the shipping on the new wheelset.
Yeah new stuff!
