Looking at various pictures it seems as though the part you attach to is a tab, and could be slotted and silver soldered, or tigged. The fact it comes in Ti indicates it can be tigged, but the style seems also to be something you can silver solder. You could ask them.
My own prejudice would be that if something can be tigged it should be tigged. It will require less heat for the most part, and use less material/weight, demonstrate greater skill, and you get a fusion bond. But if the rest of the bike is going to be lugs or something, it might affect the acceptability of TIG. Not a particularly classic drop, so you can probably do what you like.
