Yeah, opd sfbs were good, can't imagine the new ones.
You want to look for a ski that is either heavy hard wood (maple, beech, ash w/ another wood and/or metal) and poppy, or a ski that is heavy with relatively soft wood (fir, aspen as well as integrating harder woods to a secondary extent with metal if you fancy that) and very dense.
The latter set up is the best for crushing crud and absorbing vibrations and shockwaves at speed. Find a ski with urethane sidewall integration or rubber in tips and tails or along edges and you'll definetly have less trouble at speed. Generally the heavier the ski, the better it will be at speed but also take into consideration the woods used and overall build and other materials they may use. Generally heavier, denser wood, full side wall construction integrating rubber/urethane, metal in the core, though that's not always the case, and a good amount of camber underfoot is your best bet to have a bomber ski.
The very old 2013 influence 105's and 115's were crub crushers, same with the larger length supernatural 108's with rubber and metal. Volkl mantra is also a crud crusher.
