Some thoughts about my my speed whobbles:
Without loads the bike handles very well, not whobbling even at top speeds over 90kph, very good and predictable steering, fast in twisties, no big issue with side wind.
I’m running a front dynamo hub so there is a bit of weight in the front wheel. The wheels are built by me, very true, very even spoketension, running since 25kKM
The whobbling only appeared with the Tailfin which is a common and known problem. Also I’m using the longer arch since I use the Tailfin also on my dropper Seatpost bike. The weight is even more in the back. Next time I’m using the Tailfin I will try some weight distribution to the front with a little bar roll. Also a little more preload may solve the problem.
I will report back.
