George, what size hook is most commonly used to tie the "spinster"? I suspect you could use a number of different hook sizes and the appropriate spinner size to match. Would using something like sticky back lead foil to give it some extra weight be cheating or should the use of a weighted fly line be used? I like the pattern and think it would work well on some of the big brown trout I chase after in a fly fishing only section of creek I fish. However, with the addition of a spinner I am not sure the pattern would be legal to use in the fly fishing only section? They have very specific rules or what is and what isn't allowed.
