Big Mike is right, Reactors are some of the most stable kites with an awesome upwind ability. They are designed specifically for buggy use.... I have
3 and LOVE them.
4.4 is a good size, but the Reactors give a lot of bang for the buck, if the 3.3m size works for you and you only want to upgrade your kite to a buggy
machine, get a 3.5m Reactor. I think there is a brand new Reactor 2 in the for sale section, though I'm not sure if shipping to Sweden would make
buying used worth it.
As to the Beamer V, they are great kites, but you will likely find it very similar to your Sting, and they don't have the greatest upwind ability.
Toxics are good if your wind is clean and stable, but my experience with them is they don't handle dirty wind all that well. (We call it Janky wind).
Edit: just saw it's no longer for sale.... Bummer |
