i wouldn't put anyone in a cochise if they were riding in the park to be honest. And they make like 5 different cochise's. The 90 110 130 130 light etc, all different views. I'm gonna assume you mean the 90 and my answer is still no, i'd put you in an rx 100 before I put you in a cochise for riding the park.
Your post also implies that the rx100 would not be ideal for skiing in the park.
You kids need to get away from this 'park specific/oriented' boot mentality. All it is is marketing. Matching the fit and flex of the boot to the skier's individual biomechanics will allways be key.
I don't ski park anymore, for the same reasons that I don't actively seek out HIV, but I do ski in the Cochise exclusively. I don't see any reason why it would not work.

1. Wouldn't be surprised if were the same age, we all adults here, kid, really?
2. I never said park specific, I said ride in the park
3. The Cochise doesn't offer the rebound that you would look for in boot in which you could ski the groomers and drop in the park every now and then. (1 quiver boot)
3. Explanation: The Cochise is a soft boot, good you would think, but the RX 100 offers more rebound and would better suit him. What I mean by that is the Cochise will jerk to a halt because it's so soft while the RX 100 would flex but most likely never reach that point in flexing a boot where it physically can't go any more
4. FIT IS EVERYTHING
5. Flex is marketing, every company measures there flex differently, a RX 130 feels soft for a 130 yet Lange can still put a "130" price tag on it
6. Cochise series are great boots, I've sold at least 6 or 7 110's and 90's, there great, but seems like he was referring to the 90 and there are better options on the market for what hes looking to do.
7. Last but not least, you're probably thinking, well you said the RX 130 is a soft 130, wouldn't that make the RX 100 a soft 100, and my answer is NO. The RX 100 uses a PE shell with a PU cuff, like most companies do, but they use black which makes it stiffer. If you don't think color of a boot matters in terms of performance go ask any real racer if you can change the color of their boot before race day. They'll say sure but most likely won't like you very much.
8. Boot's are like tape, ton's of different options out there, some more suitable for the job than others. Example, I wouldn't use scotch tape to hold my bumper on my car, I'd use duct tape. But I would use it to hang a poster or something like that.
Just going to correct a couple of points for you. I'm fairly certain the RX 100 uses a PU shell and cuff, but if they did use PE it would be in the cuff not the shell. That is the typical cost-saving breakdown- inject the cuff in PE and keep the shell in PU.
Color does change the behavior characteristics of the plastic, but black by itself does not make the boot stiffer. PU gets stiffer by a factor of 4 when it is frozen. The color black (as in other products) causes the boot the heat up or cool down faster. So, black master badge (coloring) creates the most inconsistent flex properties as it is the most unstable color. Therefore, it could be stiffer but it could also be softer depending on temperature/sunlight exposure.
I rode the Cochise 120 last year in the park and I have nothing but good things to say about them. Never got shin bang, my feet were never sore after multiple days in the park, and they were comfy as heck. Super nice boot. I would definitely recommend it. Don't know anything about the 90 though.
In general, there are 2 main families of plastic used by the ski industry: Polyurethane (PU) and Polyethylene (PE). PUs are the "good" plastic used in high end boots, PEs are the cheaper plastic found in low end boots.
Polyurethane can be broken down into 2 types- Polyester and Polyether. This is what Lange has done here, but it would be a mistake to call them "PE".
