If we put the U connection aside and look at these 2 - Mario and Lane - in the proper context, Mario is the obvious choice.
Mario is:
Clean as a whistle - no questions about character
Proven P5 HC
A few question marks about decision making but nothing that can’t be rectified
Lane is:
A lot of flash and not a lot of substance
Questionable character
History of moving frequently
I’d prefer a HC of high character that will more than likely stay a while. Add in the fact that Mario has the U and SFL connections and I believe it’s a no brainer. Whether or not it comes to fruition is yet to be seen.
