70 here and recently switched to a Tour Easy. It's proved to be very confidence inspiring from a balancing standpoint, as your feet can instanly go from the pedals to the ground, which ain't far away. Also comfortable on rough surfaces as the long steel frame acts as a shock adsorber. Another big plus vs a trike, least for me, is the two wheeler's narrow footprint.The ONLY downside is that it's slower than a df, especially when climbing. OTOH, you can zoom down hills.
The biggest issue with bents, other than speed, is psychological, the *image* factor. Get over that and the *need for speed* and all's good. Especially with a cup holder on the bar for coffee. Or whatever.
