Recently the board software has been updated and there are some known bugs/failures:
- Avatars are currently not being displayed
- Tapatalk connection is currently broken

Those bugs will be fixed ASAP (next few days) as they are unfortunately more serious than expected.

If you find more errors please post it here: http://weightweenies.starbike.com/forum/viewtopic.php?f=7&t=139062

I am upgrading to di2 10speed from ultegra, staying with 10 speed because 10speed junior cassettes are much more common in wheel vans than 11 speed junior cassettes.

I was originally planning on buying DA 7970 from a friend, but now i am considering buying 6770 because of the e-tube system, and reformed tech. I will only be buying FD,RD,shifters, battery etc., no brakes (i have cnc brakes), or crank (pmeter). what do you guys think? I think 6770 is heavier than 7970, besides that i dont know...

Go 6770, although DA7970 is a bit better/lighter (in fact I believe it's even more reliable than the new 9070) in time you will only need a 6870 rear mech chain and 11v cogset to "upgrade".
The four wire protocol of the 7970 will die a slow death and parts/cables will become more expense/harder to obtain in the near future.
