RSX front double brifter adjustment

This brifter I am having issues adjusting has 3 positions. Small ring, trim, and big ring.

Which position do you have the trim on? Small ring with small rear cogs or big ring with big cogs? If you click the downshift once do you go to the small ring or do you need both clicks to drop it?

I've always biased my STI doubles to the big ring, so my "trim" is big/big.
1. I spend a lot more time on the big ring, so I want the range there, and the lack of noise.
2. Often, I'm too lazy to switch to the small ring, hence the need for big ring flexibility.
3. My time on the small ring is generally climbing, so the chain line is "tight inside," doesn't need trim.
4. My only RSX was a triple, so a moot point.

If I recall the RSX 7 speed brifter does NOT have trim function.

My set were for triples. Are we sure they were made for doubles?

This may be the crux of the issue...the "trim" is actually for the middle ring.

Ok, treating it as a triple with one useless position has solved the problem. Doh.

If I remember correctly, RSX 7 was triple, but there may have been an RSX 8 that may have been double.
I had a Calois that had 2x8 RSX?. RX? SLX? Very shiny stuff.

So many letters, so little RAM.
