I am a big fan of New Zealand indicators. I set them in place on my leader and apply a paste floatant to the wool prior to my first cast. Mucilin silicone and the Orvis paste floatant are the two I use - the Muculin is great and I prefer it over the Orvis - but if it is hot out it the Mucilin turns from a paste to a liquid (learned that the hard way this past summer...) so I used the Orvis in the summer. I just rub some paste on my fingers and then work it into the tuft of wool.
I have found that the indicator will float like a cork for hours with the floatant applied prior to use. If the wool becomes waterlogged I just dry it off in my sleeve. And at times I have had to reapply floatant.
The wool can alsosuspend a decent amount of weight too - I have had tandem rigs with a weighted fly and 3 split shots suspended easily with the NZ indicator where I have the same rigs unable to be handled with foam indicators.
The NZ indicator is easy to rig, (there are online tutorials that can help with tips) they FLOAT and they are reusable. And the biggest thing that I like about them is they barely splash when they hit the water - WAY smaller of a splash than a foam type indicator and NOWHERE near the splash made by an Airlock indicator or a Thingamabobber. Also, NZ indicators don't kink your leader.
The drawback that I have found is that they are nowhere near as fast to rig up as just about ANY other type of indicators. But, in my opinion the pros very much outweigh this con.
To address using Gink on NZ indicators, I have never tried it, but it might work... Also, I fish smaller freestone creeks. If the water levels are up and presentation is no so much of an issue, I revert to Airlock indicators. If they could make Airlock indicators that hit the water as softly as NZ indicators do, that would be the perfect indicator!
Hope this helps.
