Heya!
Most common str bow build is;
90 pacheon
90 fire (imbue)
90 light
30 ice
your pure str so you dont really need the phys def ice give you, you need the speed from light, light also have some nice buffs.
And fire is a must have for a str player couse of the buffs (physical attack increase) and magical defense you get from it.
If you want some more physical defense you can make a;
90 pacheon
90 fire
60 light
60 ice
You will loose speed but you will have more defense this last build cost less sp
