Would using an Avalon 741 or  S7 be profitable in a pool setting? It appears that by solo mining at the current bitcoin price's I could be around $80 profit per month with the S7 and $200 with the Avalon 741.

How much more would the profit go up in a pool setting? I do realize that every pool is different but am a round about figure would be nice to have.

If anyone is wondering I'm kind of between buying an S7 or the Avalon 741 but since the Avalon 741 has a higher TH/S rate that will probably be the best bet. I can't seem to find any S9's under $2,000 right now and Bitmain doesn't have any in stock (I know they're cheaper on Bitmains site).
