This won't help much, but the only time it struggle using my 108s is in tight bumps if I'm skiing mediocre due to the size. I think a few dedicated days would solve this though. I have a pair of older Danollies and don't notice a huge difference in swing weight.
If you stay out of the bumps, I'd go with the 108s if you take trips out to the pnw/western Canada/California where the snow is heavy and wet. If you like tight bumps/take trips to CO or Utah/or ski very frequently in VT, I'd go with the 98s.
