TJ, are you planning on demo rides this year? Last year Spyder had both models available to demo there at FWH, as well as several other vendors. Try as many as you can - what's good for one isn't always good for another (as I'm sure you know)!!
I have a Suzuki Boulevard C50 with a Lehman trike kit. I honestly should have gone with the C90 - the C50 has "get up & go", but still feels underpowered sometimes. And the solid axle on the trike kit is a bit of a bone cruncher on some roads. The trunk space is a joke, at best, but I can still get quite a bit in there with careful packing.
And the lack of reverse is a slight inconvenience, but I've learned to work around that.
That being said, I LOVE triking!! I like the stability and the greater visibility. My gas mileage isn't bad, and I can generally keep up with anything I need to. I also like the storage space - much better for traveling!
