Hi,
This photo show the connector on Futaba SVi servos:
https://rcjapan.net/futaba-servo-rec...-servo-p-17394
Although the SVi (internal connector on side of the servo) can be practical for some installations and the servo lead can often be left in plane and servo that way is little easier to take out of its mounting place in the plane my personal reason for not choosing SVi is that SVi may be one source of possible "bad contact" and also possible chance the connector would somehow unmount itself (vibration etc) since it is this extra connection point on the servo. On the other hand it is convenient to be able to replace the servo lead easily if needed (break in lead, bad connector, change servolead lenght).
For my new F3A plane I assemble now I therefore selected Futaba "SV" servos for all control surfaces. In my case one BLS171SV for rudder, two BLS173SV for elevator, two BLS174SV for aileron (I also bought one spare servo each). I bought then from rcjapan, rather much saving compared to buy from any local Futaba delaer in my country (even with the VAT, customs and shipping added). Seems good price at Tower Hobbies also on the servos You linked to.
Also this time I will dare to use S.BUS2 for the servos and will have one single lead from a S.BUS hub near the receiver back to another S.BUS hub in the tail where I connect the rudder and two elevator S-BUS2 servos. Wíth my last F3A plane assembly two years ago I did not dare that single lead trick with S.BUS. This time I will try this, to save weight in the tail with just one lead instead of three leads. But still the argument exists that it will be greater risk of loosing both elevators and rudder at the same time if anything happen with this single lead or S.BUS connectors involved.

Just read a nice article about S.BUS and S.BUS servos för pattern usage that makes good sense to me.
If anyone else is interested the article, written by Bryan Hebert, it is here:
