Depends on your riding style IMO.
If you are unhooked a lot, you should just remove it.
No problems when you get used to it, as you'll just "hook" it back in if it slips out when you dont want it to.
But if you also go out and make insane jumps often, with SLE kites and very powered - you need the dick IMO, as you dont want to let go of the bar very often in these conditions, when not needed but only because you dont have a donkeydick
And sometimes it can be a p.i.t.a when you are in the water and having a difficult relaunch, as the loop will slide off easily then - and you are not able to hold the kite unhooked in these conditions
But then again - you can trim the kite down fully when in the water, and launch unhooked - and hook back in and trim the power back - but a lot of hazzle not needed
Well, exactly the same as Satan writes I can see now...
