I'll give you a freebie from my archive for your RB. This will give you a good idea on what you can safely take to 1 (or low) and what you should take to 10, based on the skills you really want to maximize.
Large = 3+ pts to cap for each point in attribute
Medium = ~2 pts to cap for each point in attribute
Low = 0-1 pts to cap for each point in attribute (0 not meaning no factor, but sometimes every other yields 1 pt to cap)
