Could be the TCR-3, Jet-III M Ti, Jet-III Pro Ti or even the M20 Titanium. As I still don't have my S27 Cx2, I don't know if it could be bigger than anyone of those I named. Oops, I forgot about the Quark AA-2 Titanium, should be the longest one at least...
What's the point of this question? Size matters??? :thinking:
TI Quark 2 X AA, quite big, long, heavy, feels good in the hand. Bigger and heavier than an L2D. Not the most expensive or fancy I have, just the biggest Ti light I own.
