these will give you more flight time, but the same gemfan in quad blade give you more punch.

Triblades are the way
For 65mm whoops, specially brushed ones, I think these Gemfans are the way to go. The Azi are lighter and more balanced, and if they were comparable in price, I'd probably go with those, but if you plan to fly a lot, these are a bit more durable and a great in-between the 4 and 2 blade (duh, I know) but from what I've measured they tend to be the most efficient in terms of thrust and energy usage as I get a good 30s-45s more on a 250mah with these compared to the 4 blade with the way I fly.

Gemfan Triblades are awesome!!!
I'm using these Gemfan Triblades on my NBD BeeBrain Pro and just love how they grip and hug the corners for racing! They're also amazing for freestyling! No matter what type of style, these Gemfans can handle it all!!!

Subjectivity doesn't help
I dont think its appropriate to review a product without having facts. I havent measured thrust, power draw v rpm or effluxion velocity so all I can say is they look good and they fit.
I cant say if they are stiff enough as I cant tell if they flex under load either.
For durability I also cant say as I havent tested under known shock loading.
All props should come with this data in their specification but unfortunately they don't. Im sure the OEM does these tests so the info is there.
Im certainly happy with NBD.
Bought these to build a 7in 8S quad. The low kv is perfect for keeping the tip speed under Mach. These appear to be rebranded Emax EcoII, so decent quality. This quad is so powerful on 8S it's just silly. Happy Camper!
Good flier, handles the abuse a new flier like me has put it through
First prebuild from NBD. I swapped out the tracer RX for crossfire, initially had a no gyro flag on the AIO but was able to get it sorted with NBD support. Flying it is a good time and it’s held up well to some decent crashes. So far only thing(s) I’ve needed to replace has been a propeller and a M3x20 standoff. Took me too long to notice but the 2 aluminum pieces are for taking the O3 air unit from 25x25 mounting and making it 20x20.
