Its a fine line balancing lures, and very dependent on the type of hooks used. I'm pretty sure 90% of the floating sticks sit tail down, as for the sinking the only 2 I have is an Orion Big Foot 140 and a FCL CSP and both sink fairly horizontal the way I have them rigged.
My opinion is that a sinking lure should sink slightly nose down so it looks as if its trying to swim down, balancing a stick like this compromises the cast ability, having it nose heavy makes them wave and wobble around during the cast and leaves me thinking how much of my cast energy and distance is lost to that wobble. Super annoying when you want that extra 10 meters or are casting into wind.
Happy experimenting!
