Irish moss vs Whirflock in ale

I'm putting a double infusion pale ale together
using about 5 pounds of 2 row Belgian  so there is a rest for the protein I'll be including.

the yeast will be White Labs WLP011 European ale yeast

Normally I use whirlflock about half a tab.
I'm thinking of  using some Irish moss as a clarifier at the end of the boil.
I know it binds to proteins I don't know whether whirlflock does or not.

Any one have any experience using both?
Any reason to  say  one is  contraindicated  in the presence of the other?

silly rabbit~!!!
  WhirlFlock has Irish moss in it.

MSDS to the rescue~!!!

Does anyone else grind up the whirlflock tablet for easier dilution?  I powder it and add that. 

Wirfloc works great and I add it to many of my ales ---- I just plop the tablet in at 15min left in the boil. Couldn't be easier - indeed I though Wirfloc was a concentrated form of Irish Moss (sea-weed)

I used irish moss a lot but haven't since going ag.  My brew clarify pretty nicely.

Ive always used whirlflock. Pretty potent stuff. One tab could work for about 15 gal.
I don't crush them but don't see the harm. They don't affect flavor.

I've used both, sometimes at the same time.  If I'm making 10 gallons, I'll use both for sure.  It can't hurt, and at the price of either, it's not expensive to use both.

Whirfloc is basically a concentrated form of Irish Moss.
