When I had the IFS I had a Detroit EZ Locker in the front. It did increase the steering radius but it was well worth the extra 3 point turn or two compared to being open.
I found the steering to be a lot easier with the EZ Locker than the ARB I now have up front. The ARB is really a bear to steer without some sort of assist.
You will need to be careful running a front locker and 35's with your IFS. Just keep it easy on the right foot and you will lessen the chance of ruining a CV.
I don't think you're giving the air locker a fair shake here. The ARB is a full (real) locker (much stronger) and the EZ is a part-time (lunchbox) locker. Both perform the same function when going straight, but when turning on extremely high traction surfaces (slick rock) the ARB will remain locked and will require a lot more Armstrong than the lunchbox, as the EZ will normally unlock when cornering. A full-time locker also gives a little more feedback to the steering wheel when locked but that's not really a big deal. The EZ is a great part-time locker and is a great performer for the price but it's not in the same class as the ARB or the full Detroit locker and doesn't exhibit all of the characterics as the "Big Brother" lockers. Lockers + big tires + high traction surfaces on an IFS setup does = to a few driveline problems, but nothing that a few tools and spares parts can't overcome in an afternoon. <img src="/forums/images/graemlins/lol.gif" alt="" />
