I have used 3 different hex kits
My 9'0 to 9'6 boards require 20 full Hex to cover the whole nose
Current prices in USD $
Hexatraction - 20 for $69.99 --- $3.50 each --- board cost $69.99
WaxMat ------- 11 for $29.94 -- $2.72 each --- board cost $59.88
Funktion -------- 20 for $36.80 --- $1.84 each ------- board cost $36.80 (I paid $26.90 in December)
The Funktion is shown on the GenRation boards (black rails) as you can see the Funktion virtually disappears after installation.
The WaxMat is my favorite
but I just got 5 new boards - 3 required deckpads as well as hex, so I had to use the Funktion Hex pads for the noses on all the boards.
There is no real difference between the RSP and the Funktion.
The RSP may go on a bit cleaner... but you never notice after application.
The Funktion is as grippy as the RSP - they both work perfectly
The WaxMat is noticeably grippier and thicker. More of a rubber feel than the typical RSP feel.
The WaxMat also comes in colors
WaxMat is an awesome product if you are doing only one board.
Funktion is great if you want to save money.
RSP is great if you like throwing money away needlessly.
Funktion Hex with paper backing still on - figuring the layout

Shot on angle so you can see the Funktion Hex after installation

Invisible Funktion on all 3 boards
ha ha... same BPS deckpad ($50 USD) installed 3 different configurations - the bigger boards needed to be wider
