600 Want some opinons about these servos for my 550

[DAL2855]

I am looking at also replacing the servos on my 550 during the rebuild. I've found these from HK:

Mi Digital High Voltage Metal Gear Servo 8.40kg / 0.03 / 61g

Mi Digital High Torque Metal Gear Servo JR/Hitec 11.8kg / 0.07 / 58g

Mi Digital High Speed Metal Gear Servo JR/Hitec 5.1kg / 0.04 / 58g

I'm looking at the first two as cyclic servos and the third one as a tail servo. Or could even use the first one all the way around, cyclics and tail. What are your guys' opinions about these servos?

I would use no.2 for cyclics, and no.3 for tail.

Thank you Stokke!
