Hi Jack - welcome to the forum.
I would get your training done and as soon as you have passed, then get to trial your top 5 bikes ( whatever they are)
Peoples opinions change - what I can say regarding the America is its a reliable,good looking bike,which gets admiring remarks- espcially from senior citizens!
There are many other forum members who have more than 1 bike- they will chime in with pros/cons im sure...but welcome to the forum!
