What's better one surgery femurs but going over the safe limit or doing tibia?

I wanted to know if you guys agree with this because i feel like if you can accomplish your goal with just one surgery is it better athletically then doing two and doing double recovery time and spending double the money?
Pros of just doing one surgery:
1.Less money
2.Less time for recovery
3.Less scars(only relevant if your doing LON or Externals)
4.Possibly better for athletics ability if your planning doing both surgeries going at the height of the safe limit like 8cm to 5cm


Cons:
1.Can't achieve your goals
2.Possible complications
3.Could have bad proportions and aesthetics
4.Possibile worse athletic ability

Why not achieve goals? You could do a second surgery later if you want from my understanding
