The Triple.Fi 10s have a very large diameter sound bore compared to the ET 4P's.  This means there isn't as much compliance in any of the Triple.Fi 10 tips compared to the ET 4Ps. With my original Super.Fi 5s, there was only one tip which I could use due to my relatively small ear canals.  The ET 4S's I have don't have this problem.
 
I don't think you'll have any issue with comfort on the ET 4P's.

Another vote for the Shure olives.  Makes my Etys much more enjoyable.

All this is great news. All this info is very encouraging. (I'm the OP)  I'm counting the hours until tomorrow when my Ety's arrive. In the meantime, I'm loading the new Touch with ALAC's. Thanks to everyone that responded. I real glad I wasn't the only one to find the TF10's uncomfortable.

Got my ER-4P's yesterday and wrote up some initial thoughts last night over here.
