I've used both the ENO eccentric hub and the Philcentric BB. My experience has been good with both. For ss freewheeling, the cheaper option is to use a tensioner like the Soulcraft Convert: http://www.soulcraftbikes.com/convert.php But for a fixed conversion, eccentricity makes it easier than trying to find a magic gear.
I'm 240 pounds and have had one experience with ENO slippage, though it may have been that I didn't tighten the bolts enough. I currently use the ENO for a fixed road conversion and have had no slippage problems. For mountain biking I've used the Philcentric on a couple of bikes. The Philcentric won't slip because it locks in place. The Philcentric is an outboard bearing bb and you need a crank like a Shimano Hollowtech. As you can see, you can change the chainring if needed.
