I have skied both the Bandit XX and the Bandit XXX. I weigh 90kg and I am 2.75m tall. Perhaps what follows will help you select the right pair of skis for how and where you ski.
Last season I rented for 7 days 191 Bandit XX skis. I found these skis versatile in most snow conditions, and very quick edge to edge. The ski tips were a little "squirrelly" at high speed straight-lining. A good all mountain ski, and very smooth.
This season I bought a pair of 195 Bandit XXX skis. I ski primarily at west coast areas such as Mammoth CA and Whistler BC, where soft snow conditions prevail.
I found that the Bandit XXX skis are much more than a powder ski, and are very capable of handling a wide range of variable terrain and snow conditions, from Sierra cement to corn. These skis have good float, and are very stable at high speed. They are very quiet and ultra damp, and have a big sweet spot. They are perhaps even more versatile than the XX. They do not ski as wide as they look on hardpack. Rock hard frozen slush/crud and boilerplate ice were difficult for the Bandit XXX. In tight situations, with some effort, the skis will turn quickly if you keep your weight centered/forward.
Bottom line, the Bandit XXX model at the 195 length are amazing skis. If you ski mostly above the treeline, in soft snow conditions, and like to make fast GS turns, then the Bandit is your ski. I have only skied the 195, so I do not know how different the performance of the 178 and 185 lenghts are. My advice would be to go long.
Elsewhere on this site, CARDSHARP has had similar experiences with the Bandit XXX. Powder Magazine and Canadian Ski Press have highly recommended the Bandit XXX. See www.skipressmag.com
under the ski tests side bar.
I respectively disagree with what UTAH 49, RIO, and NM have said about the Bandit XXX, as my experiences have been quite different.
Elsewhere on this site you will find various opinions regarding Salomon Pocket Rockets and AK Rocket Pilot skis. I have not tried these skis, so I have no opinions regarding them.
In other forums on this site you can find some comments regarding the 2004 Bandit B1, B2, and B3 skis that replace the Bandit X series. Also, check out the US and Canadian pages of the Rossignol site. The sidecut dimensions for the B3 are 122.94.112 versus those of the XXX of 123.90.110. The tips and tails of the B3 have been redesigned, and the rubber bumpers have been deleted. The twin tip concept has been retained. A 168 lenght has been added to the other three lenghts previously available for the XXX. The topsheet graphics and cosmetics have also been changed. There was a demo day at Whistler this spring for the new Bandits. Unfortunately, every time I checked out the demo tent, all the B3s were on the mountain. Also, I have seen B1s and B2s at Mammoth, both on the hill and in the ski shops.
Separately, I have seen your Las Lenas information elsewhere on this site. I too am planning a trip this summer. When do the Santa Rosa storms occur? How often is the Marte chair closed? Where do you ski when this happens? How is the skiing now?
