Would like to see if BATMAN_V would select the higher throughput path.

Forgot something: You can also increase the hop penalty [1] on all nodes to 
let B.A.T.M.A.N. IV know that it should prefer shorter paths (as in hop
count - not as in packet loss).

But first try to increase the multicast rate on all nodes. Also make sure that 
the wifi driver/hw is actually using the multicast rate setting. For example 
by monitoring the rate with wireshark [2] or a similar tool on a wifi monitor 
interface [3].

Kind regards,
