Thanks for this interesting information.
Do you have any information regarding the response timing ?.
I presume this will be lower on the dual N-stream connection. Would like to know how big the difference would be.
Could you tell what type of bonding you have been using ?.
I have been playing a bit with bonding trying to combine two not symmetrical connections (Different speed 8Mbit and 4 Mbit). When the speed is not equal the total speed is 2 * the slowest connection. Would love to use bonding alb/tlb but that is not possible with EOIP

Your configuration does also have an advantage that if one radio link goes down the total link still works.
