CD, before you cancel your Rain SIM's, would you be able to do a test and post your speeds of you bonding your Rain connection to your fibre connection? They'll both have different latencies, so I'd love to see how that would work...
I used Dispatch proxy which is not bonding but basically a proxy that distributes threads between my 2 connections.
Here is what I managed earlier today with Telkom 4G+ and Supersonic fibre 200Mbps line. Impressive. Downloads at 31MB/s
