RE: portal frame bracing
2. angles and rods have limited spans that can travel before deflection become an issue (to solve this you can hang from the purlins)
3. I prefer rods over angles due to the ability to have a turnbuckle for installation.
4. getting angles to the right length such that they are installed correctly is hard. often they are too long this causes a compression that needs to be taken up before they can be used as the tension tie.
