Tri-Planar Vll "SE Upgrade"

Contemplating  sending my Tri-Planar Vll back to Tri Mai for his "SE Upgrade". Essentially, same carbon fiber wand and internal silver wire and leads used in his 12" U12 arm. Anybody done the dirty deed?  If so, better, worse or pretty much the same. 

I've only seen one post on the subject and that person seemed more than happy.

Thanks to anyone who responds with personal experience.  No conjecture please.
