Opinion on ST clutch

Hi all, as you can see I'm new to the forum, however, I'm not new to ST's, I have an ST that I stopped riding about thirty years ago, I have decided to put it back on the road, I am thinking of putting a new Lifan 110 engine in it, my problem is this......do I go for a manual clutch engine ( which I favor) , or do I go for the auto clutch as the original is, I must be honest, I have never been a big fan of the auto clutch but it would be more authentic, I'm interested in others views on this.

Lifan is not original by far, so I'd go with the option you prefer. (manual)
