Coachg, an RDM US cup extension can't be used without the collar.

Oops. I missed the part where we were talking only about RDMs. I thought it was US vs. Euro pins. All my RDMs are Euro. All my SDM's are US.

Our gear is stored next to the sea. The last of our guys using a euro pin quit when the second one snapped off from point corrosion at the base. When one of the pins breaks in the same way on a us base you can still sail as usual .
When both break the setup easily gets you home. On a Euro pin your rig comes in two. We sail out in the blue with no rescue available. A euro pin might have killed us,we all dumped them.

Went down last night again on a 50/50 whim hoping to get back on the horse. The wind didn't materialize, but the reef did becoming exposed on the negative tide. I few of us decided to go for a stroll to see exactly what we are riding over and where the hazards lie.
In a rare act of giving back, the reef offered up a pristine streamlined red line aluminum mast extension with US base two pin system! The reef has spoken, I am ditching carbon and staying with the US system. It was just sitting there in one of the crevices along the reef. No corrosion. No broken mast nearby. No uni attached. Just the part, alone, waiting. Its exactly what I needed. Magic!

| I still use both US and Euro. I like both Chinook and Streamline, but with Ezzy sails the Streamlined locking latch is hard to reach and engage or disengage on the Euro without undoing the strap at the bottom of the Ezzy sail. So when sailing my Naish sails I'm more inclined to use the Streamline Euro as the latch is easier to reach, but with my Ezzy sails Chinook US or Euro pin. The only extension I have had fail was a Windsurfing Hawaii years ago. I guess I'm kind of partial to Streamlined because I remember using them when they first came out, with no adjustment!!! Still fun was had by all!!

One nice RDM Euro Pin extension for use with Ezzy Sails is the North Uni.XT
North Sails Uni.XT
It has a ridge on the back to keep the tack strap seated below the release button. It has a unique pulley alignment that lets you rig sail 6:1 standard threading or 4:1 loop and go threading. With Ezzy Sails, you'd have to convert the sail pulley to D-Ring to do loop and go. Here's a picture of the base cleat

This. Interesting tip on the Streamlined extensions, I'll try one next time I need to replace an extension.
Not all Euro pin product's created equal though. Anything that's not one piece metal mold like Chinook's will eventually unravel or the pin sheers off (seen both). Tendons on the Chinook UJ are also straightforward to replace and the screws they've been using in the past don't rust/stick.
Somewhat OT. Only caution is that (all?) brands seem to be changing contract manufacturers on accessories somewhat frequently now? Just my impression. I've received substandard stuff from Chinook over the last coupe years. This WRT the poly-carbonate molding process (I figure) that's left that burned smell that hardly dissipates over time. Not a material defect really but makes you wonder.
