Flight with 4 ales..ahh, i mean ...ailerons :)
yesterday I tried the 4 ailerons setup and it worked great!
roll rate is just right, now! I would guess around 270°/s. that is for my taste sufficiantly high and still low enough not to loose orientation.
I'm preparing the video right now that will show you the difference.
My recommendation would be to go with the 4 aileron setup. If you are happy with low roll rates it is sure worth a try to enlarge the bottom ailerons (e.g. like shown in pic). that is also if you want to keep it very simple and feel detered by the "complexity" of interlinked ailerons.
I'm curious how JERBEARS modification worked out I hope he will let us know!
