Yo khuon,
Looks like you already have your other two rides just like me. I have a colnago road bike and a santa cruz superlight. THe next logical step is a recumbent. I have three of those now too. Never mind the big ha bike check out a rotator pursuit here's a link these are hand built,very fast,comfortable,visible in traffic and easily look over your should for oncoming cars during manuvers. ask for steve tell him brian sent you.
