+1 on the jump stop. Tandem shifting to granny is always a little tricky
1) Plan ahead - try to do it before the steepest point
2) Often it works better if you're not already in the largest sprocket
3) Communicate: This is the one change I'll yell out for
4) Stoker needs to back off the power, not just the Captain for the smoothest shifts (a key reason for 1))

I'd say this worked 90% for us - the Jump stop is good insurance
