I have used a Streamlined extention and matching US cup base for a couple of years now. The problem I have had with the Streamlined base is that it distorts when downhauling my 10M sail. I use a winch to down haul this, and everything looks OK but I have a big struggle to insert the cup base into the extention.
On close inspection I find the extention has gone oval at the bottom and I can't get the US cup base inside. Very frustrating at the beach. In my experience, the Streamlined base and extention is suitable for 7.5 and smaller sails only.
