Yep, I'd second that anomaly you've spotted. I'd even say, that a Pulse 170 will still fit.
Why?
1) the anomally. If you compare the Pulse with the Sabre2 they usually differ in 1 size in the same fitting category and in two sizes from standard->full fitting.
2) the above claim is somewhat real, since according to official PD documentation (http://www.performancedesigns.com/packingchart.asp) the Pulse packs 2 sizes smaller than a Sabre2.
Therefor my rough guest is the same as yours for the v308:
Pulse 170 full fitting
Pulse 150 standard fitting
