The whole reason they put the steering on the rails was to try to fix the akerman idea. I think i'll live with mine the way it is. I have had no problems and i don't have any slop. I put some superglue in the part where you put those adjusters on the end of the steering rails when i first got it because i stripped out the screws and it hasn't budged since. I have no slop what so ever.
I don't think the weak link in this setup is the rail idea, i think its the built in servo saver. When you turn you put pressure on it and it causes the servo saver to apply pressure the wrong way. I think since i have my servo saver tightened down so fricken tight that it doesn't even work
which does not allow the servo saver to "cock" itself in the wrong way. When i get my parts and drive it some more i'll let you guys know how it is working for me
