You are getting fine odds to call 2 cold for your flush draw, but you aren't drawing to the nuts.

You could be in a lot of trouble if you make one pair on the flop. 2 pair, or a 77x flop would give you a monster, but a KKx flop would make you vulnerable to a K with higher kicker.

If you make a pair or any draw on the flop, expect to put a lot more in chasing.

I am going to go against the rest of the group, and just give this one a 4. I think this is a profitable enough game that you can wait for better starters.
