A lot of bike paths are not very recumbent trike friendly. I don't think 315 is that far above the weight limit of a Greenspeed Anura as to rule it out. In fact I know someone personally in that weight class that bought a Sun against my advice. It was impossible for them to get up the gentle slope of their driveway with it or to get it inside the shed where it was kept. Traded in at a loss and an Anura was purchased and it seemed to do the job. A used Anura (I don't think any more will be made) should be well under $2K.
