Several of us have tried tail mods and find they help at one set of wind speeds, but actually make things worse at other wind speeds. There is a long thread here
https://cumulus.hosiene.co.uk/viewtopic.php?f=13&t=1753 That you might want to contribute to instead of starting another. It's completely up to you, but might help others searching for information.
I noticed your wind speeds are pretty slow - please keep us posted, especially after you experience higher speeds.
