Actaully, with a flywheel weight, running a ratio more like a 125/250 isn't that bad, as the weight helps control wheel spin.
As a test, I pulled the flywheel weight off last weekend without changing from the 14/47 sprockets, and just hated the change. The bike spent more time trying to swap ends than running straight. While I use the power to steer the bike with the rear wheel, it must be controllable to have the desired effect. We returned to the van where I reinstalled the flywheel weight, and then rode the same 20 mile loop. Much improved, so the weight stays.
