Cool pics. I have the same set-up as you. I liked the WL Tadpole after I seam sealed it and added d-rings or dutch biners to the slings to keep drips from running down.
On the sticky whoopie slings - I connect them to dutch biners that are connected to 12 inch loops threaded thru the hammock ends. If the slings are wet I just unhook them from the dutch biners so not to pack them wet with the hammock and un-stick them later.
Like the others have said - the main thing is to take the pressure off and they should work fine.
