I'm surprised I haven't seen this before. 

If an IFS is available, don't wait around for a SA.  If you liked the IFS, grab it.  If you wheel with it, and get good at it, when you go to a SA (whether through a SAS or buy a different truck) you will be a better wheeler.  Some people decide that they have a good enough truck the way it is   I've taken my IFS truck through the rubicon, and on a lot of other trails, ranging from easy to difficult.  Granted, I'm not gonna be running sluice with it, but it gets me where I want to go so far.  I've only broken 1 axle, and 1 set of spiders, both at different times, both times doing something I know better than to do, and It was compltely my fault that it broke. 

If you do choose to lift IFS, make sure you go with a kit that keeps the halfshafts at near stock angles, that'll help prevent breakage.  Aslo, get a good skidplate for the front diff/IFS frame.  I've used my skidplate to slide over stuff plenty of times, and it'll help with the damage control.

My truck has 35" tires, 4" pro comp stage 2 lift, 5.29s, and is lcoked front and rear.
