Not that there are many kendo/iaido people here, but how many people here who do kendo do iaido as well or vice versa?
I wound up doing both as at my original school, both classes were included in your monthly fee.
As a benefit, I found the quality of my strikes in kendo improved. In my own expereinces, the people who practice Iaido seem to have better form than those who dont, and have a better understanding of what they are actually doing with a sword as the shinai and iaito are weighted differently.
What about other people's experiences?
