I've taken some time to produce a few informal videos (more to come) on Product design workflows using T-splines and tsElements for Solidworks. There are two videos posted, one showing how to design a bathroom faucet and the other a flight control stick (joystick) - (Charles, I'd imagine you'd be all over this one) Both download zip include .tsm and SW files for the final designs. You don't have to have the T-spline add-in to inspect them but you will need it to edit the t-spline in SW.
