Trizact 337DC vs 347FC
#1
Can anyone help me understand the difference between the 3M Trizact 337DC and the 347FC belts?  I've done a google search and looked at 3M's info and found the following.  What should I know?  I'm in the process of buying belts for my new Viel S5 grinder (coming on Tuesday) that I'm putting on a 1/2 HP 1750/1140 rpm motor on.  Plan to run at 1140 rpm to give me 1790 sfpm belt speed to sharpen knifes.  Currently using a Ken Onion Blade attachment.  Time to join the "bigboy" party (lol) and please be kind to this newbie.

Looks like the difference is weight and recommended grinding pressure.
