Xoar / JFX beechwood props - What are the differences for Electric or standard props

[tahoelight]

I still have not tried any Xoar props but thought it was about time. I am looking through the Hi-Model.com website and see the JFX props. They are quite a bit cheaper than the Xoar sites (although not as cheap as they appear after shipping and 3.5% fees). Anyway, I am unsure of the model to choose. I am getting various sizes but as an example, they have the following.

or

12x6 Beechwood Prop for electric engines counter rotating http://www.himodel.com/plane/JXF_12x6_inch_Beechwood_Propeller_for_Electric_Airpalne_Counter_Rotating.html

Photos don't help as they are not the actual prop. Anyone know the difference in model and what I should be looking for on a Multi-rotor application?

I am getting some for a Y6 with Avrotos (trying 12x5 top and 12x7 bottom as 12x6 is out of stock.) running 4s
and an Octa with Tiger Motor 2826 550kv motors. (trying 14x5 and 15x6) running 5s
Any other suggestions?

The electric ones are made for electric motors and are thinner lighter than the standard props that are made for gas engines. I do find odd that they state the weight of the 12x6 as 20 grams, my JXF 14x4 weight 18 grams.

With those motors I would just run Graupner 14x8 on both sides.
