Stoker Kay (at 4' 10 3/4" tall) has disputed personally with Mr. Bill, and his credo, 'stoker sizing is inconsequential'!
Would your stoker wear a size 9 shoe if her actual shoe size is a 5? Sizing is inconsequential??! Yeah, sure!
In case of a panic stop, my stoker prefers to be able to get her feet flat on the ground; and for her, proper sizing is a must.
Mr. Bill is entitled to his opnions, and so is my stoker!
