Bit of background -- I'm slightly under 5ft 9 tall, weigh a bit over 80kg, middle-aged woman, recently qualified L1 instructor, possibly planning to sit L2, and have been teaching novice skiers in school holidays. I generally ski on Blizzard Brahmas in 173cm, and really like them, for pretty much everything, but suspect they will be viewed as a bit wide (88mm waist) for sitting further qualifications, bearing in mind that L2 has more emphasis on shorter turns than L1 exam.
I also don't want to be stuck with a ski that will do the job more or less, but be a noodle for skiing in my free time, should I have any. Of course I can bring my Brahmas up too, but having to go in to change skis is precious time wasted.
In local shops I've pinpointed a couple of skis, one of which actually appeals to me to ski on, and the other which may be better suited to my working brief -- but I have some concerns about its viability for free-time skiing. I can get reasonably attractive deals on both.
So, ski one is the 2015/16 Blizzard Power X8, which sounds like fun to ski and excellent on groomers, but potentially a bit of work (from some reviews I've read) when it comes to demonstrating shorter, slower turns. It's 81mm under foot, I believe, and can't remember the turning radius, though it didn't strike me as excessively large. The shop guy, whose advice is generally pretty reliable, thought it would be an excellent choice.
(I'd potentially be interested in the Latigo too, but they're not available in shops here so I'd have to buy online.)
Ski two is Kastle LX82. No idea what year, though it's unused. Given the price (NZ$900 with bindings), I'd say it's not the latest model. I'd done a wee bit of reading on these and hadn't gone out looking for them at all, thinking they'd be too lightweight or soft. But the guy at this other shop is also an examiner and he recommended this ski as ideal for demonstrating shorter, slow-speed turns due to easy-to-pressure tips. My fear is that while that may indeed be the case, they won't be as much fun to ski for a fairly hefty individual like moi. But he reckons their lateral stiffness will be ample, even if lengthwise they are softer. Another point -- the ski length he was pointing me towards was in the 160s, but I've been reading that the LX82 skis short, and even Kastle's own website recommended the 170-something ski for me.
