I've got a Sun Sport AX LWB (based off the EZ design), and just have never really gotten along with it for around here. It weighs about the same as the ICE Q I'm ordering tomorrow, and I guess after a lifetime of riding sport motorcycles, along with the odd MTB and road bike, I'm used to a lot more weight on the front.
I'm also not that good at balancing the Sun at the low speeds the hills and roads around here seem to require, so trike seems like the way to go. The Catrike Road I demoed seems to have lower gearing and is actually lighter than my Sun, so I reckon will be a bit easier on the trike.
