Viking Engine Research

Spent the evening (night) watching Viking Engine videos on YouTube, one of the most interesting was the Talks #2 - FAQs (https://www.youtube.com/watch?v=wHV0LuE8ePs). I have been debating between really two engines, the Viking 130 and the UL Power 350iS. I am very much leaning towards a Viking 130 after my evening of education.
