I a warm shack they are fine and for a barrel spring type of strike indicator they are something else....super sensitive and they show those up-ward hits really well.
There are so many opinions flying around about strike detection that its hard to stay abreast of the innovations and impossible to make everyone happy with one idea. I guess this is what drives tackle creation and the ice fishing industry itself. Great stuff.
