A lot of people like and use Navy Lifeguard's "Navy Nest" silica wick.Yesss, you hit the nail on the head right there! It's why I can't use the egrip rba anymore and hate rebuilding my kayfun. I try to use my coils as long as I can. I've had my ST mini for three months and still use the coil that was prebuilt in the rba deck.
I read some of you still use silica. I'd like to give that a try again, but how would you build a kayfun with silica? Any pics?
