I want to start aikido, but there are a few things I am not clear about e.g how can there be different styles of aikido, if there are different styles which style is the best,
How can there be so many different flavors of ice crea, kinds of cars, ways to skin a cat?
People like to do, own, eat the thing that appeals most to their individual tastes. I think i the end there is only one style of aikido. The one that YOU as a individual develop for yourself over years of work. Do't worry about the style just worry about finding the right teacher for you. Whatever style he/she does will be your style until you find your own.
