tlrsn, how did you feel on your demo run on the Brahmas?
You didn't demo? That's like buying a car from a catalog. Worse. Buying a dog from a catalog. The cheapest thing you can do when shopping for skis is the demo. Buying the skis that put the biggest smile on your face means that it'll be a long time until you buy more. Also you can demo the length as well as the model. You'll find huge differences in the feel of equally high quality skis of the same genre. The one you really like might not be my favorite, and that's OK.
How much energy do you put into the skis? How much energy do the skis need put into them for their best performance? Skis are made stiffer as they're made longer. The longest/stiffest size in any ski line is made for the biggest, strongest guy on the mountain. That isn't me nor you at 165#. If the skis are too soft they'll be like skiing on noodles. If they're too stiff they'll be like skiing on 2x4s. If they are right for your skiing energy input, they'll do their best for you. My rule of thumb, for my weight, ability, style, and energy level is to buy one size less than the max in each line. My carvers are 170, my mid-fats are 177, and my fatties are 180. Each responds just right for me. With your weight, you may put less energy into the ski than I do, and perhaps two sizes down from the longest/stiffest will give you the best response.
Buy boots that are just right for you. Boots are our most important piece of gear. Hand carry them on a plane; you can buy or rent anything else if the airline loses it. Here are six great videos mainly about boots: http://lous.ca/
What type of ski is the best where you usually ski? Why 88 mm? Would a narrower ski be better on the harder snow in the East? Then, if there is fresh snow on your western trip, rent. Or buy something suitable on eBay this year, and demo on a powder day for a Spring purchase at a close out price. There is no one ski that will be great on typical snow in both regions. There is no one ski that will be great everyday in the West (where I've skied for 40 years). I grab my 76s or 85s or 95s depending on the day's conditions, or take two pair on a trip to an out of town western mountain. If I could count the days I've skied on hard pack in B.C. and Colorado, and Montana, and Wyoming, and Utah...it's plenty. And the day's I've had thin new snow. Or wet heavy snow. Or deep fluffy powder. One ski for everything is like playing golf with one club.
