Tony,
A float rod pin real combo is made for current and not placing in a rod holder in a dead stick application. You can fish the pin any way you want I guess but if you want to put the rod in a rod holder then consider a mooching type real that has a drag in the reel. Same type of reel but with a functioning drag. The pin reel has a clicker and it is made to keep the reel from free spinning while you are traveling from spot to spot or at least thats what I use it for. Ive seen some guys use the clicker on the pin reel while landing fish which I can't for the life of me understand because it takes the free spinning capabilities of the pin reel and you need free spin while picking up slack line on the trout while they are running towards you but thats another story.
Bottom line is use the right tool for the job and the pin isn't the way to go for carp unless your trying to get them under a float in the current...
Cheers !!
