There is quite a difference in low end between an 11m Enduro and a 12m Hyperlink. The Hyperlink has more projected area so it is closer to the lowend of the 14m EnduroV2. Add to that the small packing size and weight and it will work out a lot better for traveling with than a 15m Tube kite.
... what Gunnar said.
I'll just add that yes, HL will be slower, but mainly quite different to your Enduros. It is something to get used to. I fly HL 12 with 60cm bar and strongly recommend it. It helps to have a good trim (depower) set up on the bar as well. I don't fly it with longer than 20m lines to keep responsiveness/feel crispier. If you need a compact kite for travel, I'd not hesitate and get one. It packs small and light
