Deon, I wouldn't go for a scarborough on a kayak hey, I know a few guys that use them and use them well, but ai, not for me - it's hard enough gaffing a big fish and getting it into the hatch with a normal multiplier than having to worry about holding the spool. On a boat, no problem, on a kayak, naaah....
And I like my knuckles too....
Stick with a good multiplier, they are smaller in size (kayaks are limited inside for space anyways) and are multi-purpose...
