I'm looking for a new HT Build Project and I am planning on using a SJ HT (M5) Frame. I have not been able to find much info on the changes that were made from 2009 to 2011.
Does anyone have a pointer to mods made to this frame over the past 3 years?

I have a Top Fuel SSL and prefer to go with the M5 vs. the Carbon for the SJ HT.
Carbon is stiff and light.. and (knock wood) I have not had any frame problems with the SSL... I just prefer the feel of Al on a HT.
