International-rules Kickboxing or Full-contact?

I like full contact personally more than International rules as it does not have any kicks below the belt. International rules with leg kicks and training for them really takes it toll on your legs and knees over time and some fighters get knee injuries from errant leg kicks. Knees are not such a big deal and elbows in this country are not allowed although MMA may change that since they are allowed in that type of fighting. For a while kickboxing was more popular especially in the 70s and 80s but Maui Thai has really changed that during the 90s I think and now it is about even. Many of the fighters I know will do either but if they are not good at taking leg kicks they are a little more careful who they fight with regards to leg kicks as they don't want to get chopped down.
