Ok, I do like the new paper. It doesn't just "float off" like the
Office Max did but, it did work really well. It picked up toner nice
and the toner transferred to the pcb well. One of my best transfers
yet. Soaking was a breeze. Without the clay surface, the paper
saturates quickly and breaks down. Soak about 5 minutes, and most of
it rubs off with a gentle rubbing motion. Soak another 5 minutes and
some gentle rubbing removes the rest. My wife has these magic erase
sponges for dishes & counters, ect. They're like a white dense foam
rubber. I rubbed one of those gently over the board under running
water and all of the exposed copper was clean. I was doing 12/12 in
some small areas (mils), most of the board was 16/16. I don't think I
would go any smaller with the TT (at least not with just a plain old
clothes iron) but for this and up it worked out really well and ... it
was easy and fast (exactly what I wanted it for). Boards turned out
pretty good, I slightly over-etched them (need to get a clearer top on
my container. 
For Etching I used the Muratic Acid mixed 50/50 with off the shelf
Hydrogen Peroxide (no other dillution as both are already dilluted in
the containers) and it worked very well (outside of the nasty fumes it
gives off - use outside only!!).

The new paper was Hammermill OfficeOne Glossy Paper  #229030,  $7 for
300 sheets at Sams Club. Staples should have it to.  Next order I'll
also try their Hammermill Color Laser Gloss Paper (#292253) and see
what it's like (that one's still only $8).

New photo's will be uploaded soon.
