Any feedback on VF-45 ?

We have a "test bed" having around 400+ VF45s for both MM and SM. This has been in place for a couple years now and they work well. It remains to be seen however, what 10G will require from SFFCs. Having two fibers in a single ferrule or in two parallel grooves may be the cause for "bleed over". Thus requiring a connector for each strand (LC). As for the long term SFFC, we may see the LC become the choice. The LC may already be the best for SM.
Since we can do an angled polish on the VF45, we are even deploying CATV over some of them. The only thing is two fibers are terminated in each connector but we only needed one for CATV.
The only (big) concern we've had thus far was finding hybrid patch cords...specifically with "competing" SFFC manufacturers. We had no problem finding ST or SC to VF45 but had problems with MTRJ to VF45 cords. Manufacturers were making a "special" two strand per buffer cable for their own SFFC so it was a problem trying to terminate an SFFC from brand "A" to the cable from brand "B". Sure they could assemble it, but no one would guarantee it. It took from seven to nine months to get the VF45 to MTRJ cord figured out.
We initially looked at SFFCs for a possible deployment of FTTD. It was easy to terminate. It was cheap (less than $3.00 for two strands) and reuseable. Though we didn't use this approach for this particular cabling project (a dorm with 520 rooms), the centralized fiber design is intriguing. We did not use this design due to us wanting to send voice, data and video (CATV) over the fiber (only). Data was simple but the voice and video was not ready and too costly.
I know of a few campuses that have around 12k to 15k of these installed.
