Wow, your experience with the Silque was twitchy? The Emonda is more of an aggressive racing geometry, so...
My Silque is super relaxed and stable compared to my Kuota and fits like a dream. It's an endurance bike, not racing geometry. But, that's why there are so choices, so we all are pleased. I know nothing about the EVO, but the Amira also has more aggressive geometry.
Buy what feels right.
