My 300 is not as fun to ride as it once was (limited power in lower gears, hate it).
4RR will need frame sliders and led lights; both need suspension work.

Thoughts?

Ok, both. That way you have a bike for nearly all occasions. But seriously, it sounds like either a 400 or 500 is your huckleberry for sure.
