You should not have to change out your serving.
Get a good nock. Buy Beiter nocks for the arrows. They are, without question, the best aftermarket nocks available and I can assure you they'll fit your serving just fine (and come off the string much cleaner). Beiter is all I shoot.
What nock does your arrow use? I'm not sure what the Axis "nano ST" is - same thing as the "n-fused" axis ST? If so, I think it takes an X nock. The X nock is the worst nock Easton makes (g-nock is the best IMO). The X nock grips the string WAY too tight. I just picked up some ACC Pro Hunting arrows and they take the X nock. I replaced them with Beiter insert nocks. (If is not the X nock find out which one it is and get a Beiter replacement - they make nocks to replace all the easton nocks....and many others)
Call Lancaster Archery and order some Beiter insert nocks in size 5,19 (I believe it is) - verify with them that this is the correct size but I'm pretty positive it is. When I first called they didn't think Beiter made a replacement for the X-nock but the guy went out into the shop and tried a bunch to find out and called me back (that's customer service for you!). Anyway, we found out that the 5,19 size fits perfectly. Switch to these nocks and you'll never go back to stock nocks.....trust me.
