trick is... find height challenged people to make yourself look taller!
I'm 6'7" and look pretty darn huge in suit. Helps that I am 270 lbs as well ;)

Personal Suits from 2008-2011
"Countersnap" the black tiger with  bushycat in 2008
"Marf" with  Dibbun in 2009
"Snap-bo" in 2010 The mohawk added a good 8 inches on me ;)
"Salvo" in 2011

Countersnap (2002-2009) is in a landfill somewhere... suit just got too old
Marf has a new owner and still exists showing up to cons from time to time.
Snap-Bo and Salvo have new owners as well.
