To avoid Shooters Hill, I would go down Nightingale Place into Plumstead Common Road, right into Kirkham Street, right again into Swingate Lane and then Glenmore Road up to Welling. Easy peasy :)
Nightingale Place is the only 'real' hill on that route but is fairly short by comparrison to Shooters Hill.
OK thanks, I'll try that tomorrow.
Peace
