Daisys
I am used to shooting with Daisys that are very sensitive. I use 1/4 inch ball bearings on mine. The bearings are mounted in aluminum hubs that I glue into the back of the Daisy. A lot of work, but they serve me well.
At the Nationals this year, the Rotation I was on had a Smiley flag with daisys that, for our purposes, were useless. most of them hardly ever turned.
I use my daisys in the very light conditions. They will usually turn when others are showing nothing. as soon as the tails start reacting, I watch the tails.
I only have about 10 spare wheels, (10" Artline), left. The type I use are not made anymore. I take care of the ones I have, not letting them get blown over or shot up. A while back, I bought some really thin metal 10" fan blades from Graingers, mounted the same 1/4 inch bearing, and tried oned. Just too much mass. The break away inertia was just too much.
In my opinion, if the daisys are not the most sensitive part of the flag, then you might as well take them off. At places like Seymore, where the wind always blows, I will often not put them on.
For getting flags plumb with the world, I have always used cheap camera tripod stands. I can adjust each leg individually with a little level. I have never used anything but these. I take all the stuff off the top, and install a little adapter that has a 1/4 inch shaft on top for a ball bearing to set on.......jackie
