Replying to Kartels size opinions

Hi, new member here. A bit of fact first. I'm 34, 6'3", 205-210#. Home region is Chicago, and get out on the trash hills regularly, but not as often as I'd like. I've been snowboarding for the last decade, and decided recently that I wanted to get back into planks. My last pair of skis were straight, unshaped dynastars in 195cm. A lot has changed over the time I've been gone, and its a bit overwhelming to research.

In my research I've learned a ton about boutique builders, and I dig the effort and care that ON3P puts into their product. From their available ski lines, the Kartels seem to fit my on snow style. My question can be broken down into 3 parts;

1) score some 2015 k98's in 186 (too short?)
2) score some 2015 k106's in 191 (too wide for midwest?)
3) wait the summer and repeat same questions for 16/17 models

I am generally of the philosophy that you buy once, and cry once. I'd be relearning any ski I buy, and I do take 2 weeks out Denver/PNW way each year. My on snow style is to seek out natural features to pop off of, but would totally like to get more park time in, ideally 80% all mountain, 20% park. Would love to hear from the groups opinions.

Thanks,
Mark
