Nice dies, but... - Redding Reloading Titanium Carbide Sizer Die

I'll start by saying I've liked and used Redding dies for years with rifle reloading. I've usually only used Dillon dies for pistol and been perfectly happy with them. Except for 9mm where recently I have had to start using lube for sizing even though they are carbide. I tried this Titanium Carbide die from Redding because their adds say it's smoother than regular carbide because of the molecular structure and maybe it would work without lube. Wrong, I couldn't tell any difference between this die, the Dillon and a Lee as far as ease of sizing.
I would finish by saying it's a fine sizing die but at that high of a price I'd stick with other brands.
