You'll probably be ok, just ordering 1 orange spring. (The bottom). $10.
Besides, you might try a goal, to get down to the weight of using 2 black Springs, medium, which is a max of 200. That's what some of my customers expressed they intend to do.
Some people also feel the springs are too stiff, so maybe try the two blacks, and see how it feels, before ordering an extra spring. Note that Cirrus always supplies two extra softer Springs with each set. And you can stiffen them up by using the tuning guide, and Allen wrench. 215 won't hurt the springs at all.
