Ok guys, after a couple hours of cussing, thinking I tore my tips up, and in general, frustration, I managed to fit some Shure black foams over my UE SF3s (Again, I can only assume they're the same stem as the Triple.fi's since Comply makes the T500 for both models). Initial impression? The earpiece with the foam fitted on it is louder than the one with the biflanges. Bass is brought forward a little, and the highs take a step back. It wasn't as bright as it was before. Darker, I think, is the word. I haven't had the time to analyze it any further. However, the biggest difference I noted was that they stay in my ears even if I bump them. The biflanges would lose the seal if you tapped them. Isolation has took a step up as well.
Getting them on:
You know that thread? The one that says "stick them on pliers then shove them on your tips"? It's not that easy, in my experience. Plain old stick them on your pliers results in a tip with the tubing barely larger than it was at first. One of the problems I encountered was that the tip would be stuck on the pliers, and came off so slowly that the plastic (being fairly elastic) returned to it's orignal size by the time it came off. I even tried putting some vaseline (probably not a good idea. I'll warn you if my tips disintegrate in a months time) along the surface of the pliers to make extraction faster, but the plastic is damned elastic. I shoved those tips down to a point that was wider than the SF3 stems, took a shower, came back, got those tips off in maybe 3 or 4 seconds, and they still wouldn't fit.
It was time for drastic measures.
One person found that heating a drill bit (with a torch) with the tip stretched over it would get them to be stretchy enough to fit.
Ok, a bit too drastic.
What I did was fit the tip down as far as it would go (lube helps), then leave the the tips to stretch for a while. 20 minutes worked. Afterwards, stick the tip of the pliers with the tip still on into a cup filled with hot water (from a boiler) to heat up the pliers. You don't need a lot of water, just enough to cover the pliers exposed from the top of the tip (try your best not to get the tips themselves wet). Then I opened the pliers to get maybe 3mm (1/8") between the pliers. I let the pliers heat up with the stretched tip over them for about 2-3 minutes. After I decided that my fingers were numb enough, I got the pliers out of the water, but maintained the tips in a stretched position.
The next part needs to be done fast.
Close the pliers and slip off the tip as fast as you can. It should come off in a second or less. Then jam them on your IEM stems until they fit. Push one side in, and twist/push on the other side. Keep pushing. If they don't go on, and you've given up, try the process again from step one.
No pictures, since it's rather hard to take pictures with no hands. My pliers were a pair of small needle nose pliers, with 2" long "arms", and about 6mm wide half way down. UE stems are about 5mm across.
I will note that the tips are rather stuck on afterwards. They don't even twist around, let alone pull off. I'm not sure how I'm going to go around cleaning them.
The black foam also come with a neat package. There's instructions, an addendum (which appears to list various materials/elements that may be in the manufacturing process, but I can't read the Chinese), and an ear wax remover similar to the one UE packages with some of their earphones. Also, a bag to keep the tips in after you destroy the packaging. Not bad.
Canadians can get it through Shure for $17.50 CAD, $9.50 ground shipping (Purolator next business day, ground). It took 2 days to get here (ordered night of the 14th, processed 15th, sent to Purolator end of the 15th, in transit 16th, delivered morning 17th). Not bad. It'll be faster if you live on the east coast. If you want a tracking number, you'll have to bother them with an email. They're pretty prompt about it though.
Another option is eBay, but the seller's American and selling it for the same $28 (free shipping). Meh. I don't know of any other alternate sellers.

Further thoughts:
Piano and cymbals definitely took a hit. Vocals are a little darker. I wonder if cutting the ends of the tips off will fix this. The isolation brings more bass than the biflanges did, but I'm kind of put off by the loss of impact in cymbals and piano. If I could get the best of both worlds...
