Compared to carabiner, the pulley needs less force, because of practically frictionless wheel. The pulleys are available in many sizes, buy one which can take all your weight (and some more), so it will not be the weakest point in your landing "system".

Well, I have a similar device....mine is called a rescue pulley and is intended for larger diameter ropes (like climbing ropes). The wheel is nylon, and now has a big grove in it where the kite line cut into it, rendering the wheel fairly useless as the line now just cuts the groove deeper. (Patrick Prosser describes a different problem but same end result, useless device, in the Gloves thread.) Is your pulley well-suited for smaller diameter lines? What's the wheel made of?

(Patrick Prosser describes a different >problem but same end result, useless device, in the Gloves thread.) ?????? How many walk downs it worked? Tens, hundreds? Does the line slide on the wheel when you use it? >Is your pulley well-suited for smaller diameter lines? What's the >wheel made of? No, the wheel width is not same "size" as my flying lines. The wheel is about 20 mm wide, the whole pulley weights about 400- 500 g. The wheel is non metallic, but I don't know exactly what. Well, if the marine pulley is as useless as you and Patrick predict, I should find it out pretty soon. However, if I can rescue a kite and/or avoid injuries in a "heavy" landing situation, just once - the pulley is worth of it's price.
