Marvel Super Heroes/FASERIP: Additional Damage Revised

I've revised my FASERIP Damage Bonus originally posted here. 

If the roll of a d10 is even you gain a +1 Column Shift per die and if your roll is a double and a success you gain +3 Column Shifts.

Example 1 - My roll is a an 81 so I gain a +1 Column Shift to damage since one of the dice is even.

Example 2 - My roll is a 64 so I gain a +2 Column Shift to damage since both are even.

Example 3 - my roll is a 95 so I don't gain a bonus to damage since both dice are odd.

Example 4 - My roll is a 77 so I gain a +3 to damage since my roll is doubles and it succeeded and even or odd doesn't matter.

That's it. It's fast and fairly straightforward.

Marvel Super Heroes/FASERIP: Additional Damage

I love the old TSR Marvel Super Heroes/FASERIP rules and its an old favorite of mine, however I would like some random element to damage and have two different options:

Option 1: When an attack hits a target roll a d6 and on a roll of 1 or 2 the damage increases by that many column shifts and on a 3-6 nothing occurs.

Option 2: Works as above but when you roll a 6 it counts as 1 column shift and you preroll the d6. As long as you roll 6s you keep increasing the column shifts, but a 1 or 2 are ignored on all additional rolls.

That's it. Pretty straight-forward.

Excelsior!
