Thanks for the info guys. I think I'm just going to go with two 15s which will get me over 2".
On a side note I'm not sure my framing is going to pass and I may be screwed all together. I'm not sure I can double the floor joists in the second floor if the inspectors require it. The second floor is finished and I'd have to demo quite a bit to double the "tail joists"
