Not to nit pick- and I know what you are saying- but for your own benefit, get the decimal places correct. You mean to type 0.060", 0.045", etc.

There is- generally speaking- no difference in the rings used between these different those two compression ratios.

Now, there may be a different ring called for if the engine will be run at an exceptionally high rpm (generally thinner), and sometimes they'll be made from a different material (if nitrous or super-/turbocharging is to be used), and there are different ring tensions used for different applications, but generally rings will be the same regardless of the CR, all else being equal.
