6'2" | 35-1/2"... how about you?  Have you tested various lengths?  Do you just follow the generally accepted rule of thumb regarding physical height and length?  I won my putter decades ago at a company tournament.  It was a gift certificate to the pro shop and I dabbled with a few before choosing the B61.  As it turns out, it's the right length (or very close) for my height based on the rule of thumb.  Whether it is ideally suited for me I have know idea... yet.
