the question is not whether you should use ultraedge or midgrade for dueling. Ultraedge is a different blade in nature not in its sturdiness.
Basically, Ultrasabers offers 4 types of blades.
1.Standard Midgrade
2.Heavy Midgrade
3.Ultraedge standard
4.Ultraedge Heavy Grade
Ultraedge Heavy Grade is the most sturdy, has the most weight and is the best for heavy dueling. You should NOT duel with the standards blades, if you go heavy dueling. Standard blades ar good for shows, for light dueling, but they will break if you are into heavy dueling. Not to mention that they WILL definitly brake if you use a stardard migrade vs. a heavy grade blade.
The difference between Standard blades (types 1 and 2 in my post) and Ultra Edge blades (types 3 and 4) is the way that the lights travel to the blade. UltraEdge blade are bright, and the blade has a more "full" aspect. it is illuminated uniformly. Standard Blades have a film inside them that helps reflect the light, they tend to be brighter, but only the first part of the blade, the light tend to dim close to the tip of the blade.
Bottom line, if you are into heavy dueling, definitly go with a UE Heavy Grade.
Good try but incorrect.
1. Ultra-edge mid-grade = trans-white 1/16 inch walled blade. Known outside US as white thin walled.
2. Ultra-edge heavy-grade = trans-white 1/8 inch walled blade. Known outside US as white thick walled.
3. Standard mid-grade = clear 1/16 inch walled blade . Known outside US as clear thin walled.
4. Standard heavy-grade = clear 1/8 inch walled blade. Known outside US as clear thick walled.
The only difference between ultra-edge and standard is the color, white vs. clear.
Mid-grade blades are suitable for spinning tricks and light contact.
Heavy-grade blades are suitable for full contact combat sparring and advanced full speed contact choreography and just about any amount of beating one can apply.
