Radial front spoke tension

I built a new wheelset for one of my singles to replace its ancient Rolf Vector wheelset. I went 20H radial front with 110kgf and 24H 2 cross rear with 120 kgf drive side. Rims are Kinlin XC279 and spokes are CX-Ray.The bike is a carbon Trek 5200 which I bought new. I weigh about 145 and am fairly light on the front end. I've been using 90 lbs. front and 100 lbs. rear on 23mm 4kIIs tires.

The new front seems to transmit much more vibration than my old Rolf 18H radial front. The rear feels fine. If I have the dimensions of the Rolf spokes correct, my Park TM says it is tensioned to ~65kgf.

My question is: should I back off the tension on the front? If so, to what? It seems kinda crazy to have such high pitched spokes on such a lightly loaded wheel. Of course I could also back off on the tire pressure but I liked how the bike handled at these pressures with the Rolfs. I understand that many riders use lower pressures with wider rims like the Kinlin. Still, the question of spoke tension remains.

I'll be out of town tomorrow, but will respond to suggestions as necessary on Monday. Thanks in advance.
