since you are getting it with a 710mm set, why not get a 690mm so you can try out which is best for you. i have tried both and i prefer the 710mm, plus, they're cheaper than 690's sometimes. 710's have a more floaty feel and they auto a bit better than 690's. 690's will make your heli flip and roll a bit faster though

you can't go wrong with either since you will be using it on a fine heli, a 90size at that

i'm not sure what size the stock tailblades are on the freya. i think they're 92mm. some have used up to 105mm. i myself prefer to use stock tailblades on my helis since they work really well

Stick with the 710mm blades where possible. I know of people using 690mm on heli that have tired engines and will be a little less stress on it.

690mm blades only really starting coming about for helis with wider blade grips (such as Align and maybe MA) when they were having boom strikes problems.

If your motor is a little tired, try the 690mm. I'm actually using 690mm on my FBL D3 only because 710mm we not available at the time. Also in saying that, the Eagle and 90 FBL heads have wider grips, 14mm overall I think, so 690mm blades do become a very viable option in those case as well.

Also, with the tail ratio of the Freya, go with 95mm blades, we have had vib issues using larger. 105mm don't seem to be happy on my D3's.
