XXIO 8i: 369g, balance point 30.5" from butt
PING Rhapsody 8i : 384g, BP 28.5" from butt
PING Rhapsody 7i : 378g. BP 28.5" from butt.
PING 7i is same length as XXIO 8i.
Note: this is NOT apples to apples since SWMBO had me install GP Tour Wrap 2g midsize grips on her PINGS. The numbers could be a lot closer (maybe identical)......if I knew the weight of the XXIO grip.
I could remove the grips and measure weight and balance points, but they're not my clubs.
