I would like to get a 120mm for those rougher trails and was thinking about the Fox with a 9mm QR. Do I really need the 15 or 20mm through axles. I weigh a jaw dropping 135lbs and never had an issue with flex, plus I really don't feel like buying new front wheels unless it really makes huge difference. Any thoughts?

what wheels do you have now? they may be convertible.
Do you need it? no
do you want it ? yes, it will help stiffen the front end

I wouldn't look at it from the perspective of travel..though it plays a part in much bigger travel bikes because the stansions are significantly longer. At your weight, unless you are a very strong rider, you may not notice a difference. I can tell you that I could feel a difference between the 20mm T/A and the 9mm, but a tapered headtube may have added to that as well as having stiffer wheels.

I would suggest going for the 15mm if you do, I have read about Rockshox changing to 15mm, and 15mm will be the standard for thru-axle. So if you bought a rockshox now, it may be harder down the road to find 20mm hub wheelsets..unless they continue to make the kits. Which really hits me, because I only use Rockshox forks, and mine is 20mm..and its only 2 months old.

by the time 20mm dissapears (if ever) he will have worn out the fork and wheels.
I doubt RS will drop the 20 anyway since they have a patent on the maxle, plus everyone makes 20mm

I agree about 20mm not disappearing for a while (if ever), though you will probably see it disappear within certain market segments. Kind of like how dual crown forks have been relegated more and more to pure DH while single crown forks take over the other market segments.

Also RS is already producing fork using the same Maxle design in a 15mm version, and their patent does not appear to be specific to just 20mm axles, and I would not be surprised to see them go down this road further in the XC/Trail market
