I noticed Donny FL has a new ldc out...

"scrane"What he needs to make is a skinny LDC.
How skinny did you want it? The Tanto and Koi are skinny already IMO. Any skinnier, the effectiveness of the LDC will diminish, to compensate you would need to add length. I could be wrong, but that's what I would bet on. 

Donny has come a long way over these few short years. He has evolved his craft to a fine effective work of art. He has the quietest and nicest looking LDC on the market. IMO. He goes steps beyond any manufacturer to develop both the external visual appearance and the internal baffles for efficiency. DonnyFL really has a LDC to suit most needs, from big to small not just one size fits all. Any LDC you pick from the line up will not let you down.
