I'm late to the party, but didnt notice this thread. The ringplus deals do come up fairly often so this will still be useful if you can wait around. The bbq brisket plan is a mad plan, so it uses Sprint voice rather than the secondary network that the free plan s have. No ads on calls, and none of the latency/unreliability issues of the backup network. The data is weaker than the BLT plan offers. So if you're after voice, its the bbq plan, if you're primarily interested in data, the blt will give you better speed.
The surfing reuben seems to combine the worst of both options. Backup network for voice, plus throttling and "research". The cost is all upfront, and I don't like that either. But its a very good option nonetheless if it comes around when you need it and there isnt something better.
