Sigh, as someone who owns 8 bikes, your analogy does hold some water. But I have taken my road bike (compact crankset) onto single track. Takes a *lot* more finesse to manage it, as well as a lot more anticipation, and dang it, there are just some short little hills that I just have to get off the bike and run it up!
I guess the same can be said with the kites. Each has a personality that its best suited to. And while I can take a road bike into single track, it is sooooo much more work to do, and I still won't go blasting down a rutted hillside with it. From the sound of things, I think you'll be (like most/all of us) getting a quiver of kites.
I will say that I favor my vented kites when I can. The vents seem to smooth out the bumps in the air and make the kite less twitchy. Its such a noticeable effect, that I tend to go for my midvent or vented, even when the wind conditions would favor a full sail. It only when I spend more time working the kite a lot to stay in the air, that I switch to a full sail. YMMV
And like every one, welcome aboard!
8 bikes you sound like the guy i work with hahah. the hole road bike off road thats why i have a cross bike, best of both with out shocks. tho i do favor the 130mm travel on the mtb haha.. but enough about work. the point is every condition is going to call for changes or differnt rigs, same goes for my rc flying. i think i will start with full sail, if the wind gets higher then i can fly in, ill pull out the one pictured in my avatar and get a work out . best thing for me to do is hope its windy wednesday night so i can try to fly the sle 1.5 my friend has. may try to get some pics or video
