Hello everyone.  My first post here.  I have been reading the threads here and learning a lot...especially this thread.  If I might ask a few questions in regards to these dual miners.
My questions might lean towards some general bitcoin and litecoin mining questions but in regards to using these specifically.

I am building my first litecoin mining rig and ordered 3 of these dual miners.  My question is whether it makes sense to dual mine with them.  Does it make sense to utilize the bitcoin mining function?  Could you earn at all running 3..10 of these for bitcoin?  Is it more of a "mine solo" all year lottery and maybe get lucky on the bitcoin?  I am curious what the experienced miners here will do with them.
Thank you.
