Time for a new ones. I have mainly used Chinook Carbon RDM mediums and always chinook UJs, US pin style. I have snapped a fair few extensions in waves but just put this down to normal behaviour.

But at roughly $230 for an extension and $120 for a UJ I think I should do some sniffing around this time. Probably end up with the same unless there are any other amazing recommendations. The last one was a technolimit which seem fine, except the pin holes have worn to ovals. But that may just be because it hasn't snapped first unlike previous.

Not sure if its fair to comment on actuall shops stuff ??, but in this case I seen surf and sail do their own for 109 extension and 80 UJ. look just like chinooks, are they made by the same group ? Any feedback, or is it a case of you get what you pay for ?

What else have others used?

"Streamlined" We use them too, and their 2 bolt "quick lock" deckplates. As close to bulletproof as you can get. surfsail has them in stock.
Bought one after extension failure in the LOC a couple of years ago and that is all we use now.The original Streamlined universal still looks fine even though some big k's have been done on it.

Just changed from chinook europin UJ to streamlined - big weight difference. I've never broken a chinook, and never heard of the streamlined breaking.

Extensions either chinook or streamlined.
