Well let's just say that I haven't seen any extreme paddles missing the middle portion of the paddles. I have with the regular haulers.

I don't know about specifics but I wouldn't want to run paddles in hard pack anyhow.

 

i just purchased a set of 21x12x8 10 paddle extremes for my 686 and im going to try them out for the first time this weekend. i was actually going to go with 21x12x8 extreme triple buff but they were all out. i have allready ran a 10 paddle extreme on my bike and it got out of the hole like a madman!

 

I used to use Geckos but now i use double buff extreme haulers 20-11-9 8 padddle and picked 2 bike lengths ,I have a mild CR686 and it made all the diffrence in the world. I was only racing on the flat drags and not the hill which i prefer,they will be out on the second ride at Glamis halloween along with a tucker +3 swingarm (I hope) to keep that front end down,which is almost impossible draggin and dropping the clutch and popping a whellie thru 3rd gear..
