Brompton gearing

[LEE]

After earlier posts where I started with the Std 50T S6L.   I'd found it great until touring or in hillier regions I then swapped for the 44T.  This was much better when load lugging or going up hills, but I missed the top gears as I'm not a very spinny rider.  So for £60 I've gone for a Stronglight 50/34 Compact double which gives me back the lovely big ring back but with a granny geared system that is great for touring and lumpy terrain.  OK it's manual shift but the 34 is more usable than I expected.
Didn't need to change the BB and took the opportunity for a new chain and rear sprockets.  Fab.  Got an S12L now

Do you "heel-shift" between rings?

I think it's possible to heel shift from big ring to small; but not from small ring to big. I swapped the original
ring for a Shimano Dura Ace model; lost the pants/trouser protector in the process. Now when I shift; the chain
jumps off to the outside sometimes. It lands on the spider of the crank; I'm able to push the chain back using my
heel:

I did something similar with a Spa cycles touring triple, but with the biggest ring replaced by a chain guard, giving me 28/38, on a 20t rear, on a sturmey archer 8 speed hub. It's pretty good at going up hills, but I was still defeated by the big climb up to Black hut on the Isle of Man TT. 417m of ascent was a killer...

Not tried yet!

Easier with a toe, but that requires foot retention.
