I just purchased the new Zealand kit and so far have been pleased with the results.
I have used Thingamabobbers for years and leader kink has never been an issue as it does no damage to the leader and a good tug for 30 seconds or so takes care of the kink. I discovered the glow-in-the-dark Thingamabobber years ago and use them exclusively - not for their glow-in-the-dark properties but because they usually look about the same color as foam or other 'stuff' in the surface film, and I can see them well in most situations. When there is glare on the water I switch to a black model. I also don't use the larger sizes I usually stick with the x-small for smaller creeks and the small size for anything else.
I'll give my report about the NZ indicator after putting it through the paces during my winter fishing.
