It won't matter which you use, as soon as you fit it to your scope the clouds will roll in and the rain will begin.
My latest purchase, a Baader Click-Lock Cool Ceramic Prism arrived this morning (thanks Matt42s) and for the first time in eons it is raining in Canberra.
The 1000 Oaks filter would be my pick, the main thing is to ensure the surfaces are not damaged by careless handling and that when it is fixed to the scope it is secure.
I recommend a secondary retaining system. On my last objective lens solar filter I attached velcro strips to the filter (use a hole punch to make a small hole in the velcro strip and place the filter retaining screw through the holes. The other half of velcro was adhesive backed and was wrapped around the scope tube. If you use this method use the soft 'loop' part of the velcro system on the tube and hook part for the strips,
that way your OTA won't collect every bit of lint and hair around. With the 1000 Oaks filter which is a slip fit I suggest you use the adhesive backed loop velcro around the filter perimeter as well and then use the strips to bridge between the two bands of loops.
If you are looking through the scope and someone should pass by and knock the filter from the scope the devastating effect on your eyes is instantaneous (like a 1000 welding flashes at one time).
