Stringing with Kevlar represents a bit...
...of a challenge when dealing with what tensions you should use, especially if you're used to a more traditional string set-up. I see you're using Live Wire as your cross. If that's the case, I'd try it WITHOUT dropping my cross tension. Why? Couple of reasons.
First, Kevlar's feel is essentially "dead". It doesn't really impart any feel of its own per se. So, for many, it feels the same at 55 lbs. as it does at 60 lbs. Second, Kevlar holds its tension really, really well so you'll get a really consistent playing racquet tension-wise. Since you're using such a playable multi as your cross, I'd definitely string it at your normal tension to start with. If it feels harsh or boardy to you, you can drop it from there. But I think you'll find that the playability of the Live Wire will really soften the Kevlar harshness.
Back in the 90's, I used to use Ashaway 17g Kevlar paired with Natural Gut crosses...an early hybrid many touring pros used at the time. The Kevlar gave me a muted, boardy feel, while the gut took away a lot of the harshness and provided a good bit of playability. I've since moved to poly as my mains with nat gut crosses, but the feel is essentially the same for me, muted feel with very good playability.
I still like my Kevlar though...I have 18g Forten Thin Blend strung up in my old school Yamahas! Secret 04's strung with Kevlar...now that's STIFF!! :twisted:
