im glad i chose something out of most of your comfort zones.
Then it will push you to try something new, and to step out of your safety zone.
It will hopefully make you explore a new path.
Also think of it like this though,
you may not be comfortable with iso - but by the sounds of it, so are most people.
So even if your iso isnt the greatest around, your opponents might not be the greatest aswell.
So even if your not sure about doing iso, go for it anyways - who knows, you might just get lucky.
