I demoed the Super Bro last year and pickup up a 07/08 188 SS Pro this fall as my hard snow ski. Unfortunately I have not been on the 188 SS Pro yet. So I'm a couple week from a being able to do a complete comparison.
Me: 230#, grew up in New England. Ski in Tahoe now, which does occasionally get some hard snow like New England.
The Super Bro is stiffer.
Super Bro: Likes to make very large fast turns. It's profile seem thin and straight. It did not seem like the tip would raise up on top of any mash potatoes or corn type snow. I did take the ski into some narrower terrain with bumps. The SuperBro was unwieldy (even compared to a 194 Legend Pro I own). Basically short turns were not the SuperBro things. Which seems like it might be an issue back east. For me the SuperBro is good for maching on groomers and wind buffed snow.
For corn, crud and mash potatoes, I would want a wider option.
188 SS Pro: The SS Pro is little softer in the shovel than under foot. I'm thinking that the softer shovel will better in crud and the occasional bumps. I might have the SS Pro out in a week or so. I'll let you know what I think.
BTW: The best ski I have been on in a while for what you want is a raceroom 05/06 194 Legend Pro. excellent hard snow edge hold and wide enough for funky snow. warning: new Legend Pro is softer.
