Before I start; Im not trying to question the viability of your floats; in fact I love your Stick/Avon floats and even the ones that could be used under the tip of a Pole on running waters.
However having fished for many decades with wagglers on many different types of stillwaters and in most situations; I fail to see any advantage of using wagglers (which are primarily designed to be used on stillwaters) which have
both an upper body and a lower body regardless of their profile shapes.
I should imagine that casting any real distance with a
two bodied waggler would be quite a task, even more so if you have any wind to contend with.
Wagglers are nearly always attatched at the bottom only and on the strike the float tip will usually just collapse, and putting another body at the top of a waggler would just be adding unnecessary bulk.
The only exception that I can think of is when a very small sight tip is used above the water.
However i can see that your body shape would present less resistance on the strike and I can also see the advantage of having a shaped body (and possibly a shaped stem) on a waggler which is designed to combat surface tow and keep the float still in a wind on a stillwater; such as a
semi-loaded Onion waggler or a wind-beater.
The aim of such a float would be trying to minimise surface drift caused by wind, which is trying to push the float downwind, and maximising any undertow, which is trying to push the float body in the opposite direction; therebye cancelling out any movement of the float or even getting the float to drift along with the undertow (which would be more natural); plus on the onion float; having the weight in the bottom of the float to aid accurate casting of any distance in a wind.
Fig: A standard (semi-loaded) Onion Waggler (some have insert tips) which is great for fishing at range both in or out of wind.
NB: I’ve highlighted ‘semi’ in ‘semi-loaded’ to emphasize that the ‘onion’ is not a fully loaded float and is only partially loaded.
If you do decide to make such a float I would love to test it for you; although it is still possible of course that your body profile may not work in this situation after all, but it might still be worth trying.
