& a friend overly suggests to go to steel moto rims & use 10 guage spokes becuase the rim can accept them.
Pound for pound, a steel rim will always be weaker than an aluminum rim. It will also always be single wall, so it will be weaker in that way compared to a double walled aluminum rim. Yes, you can double the strength of your wheels that way-- by making them 10x as heavy and only compatible with really slow heavy tires. Not worth it.
The failure you showed from your wheel was caused by spokes that were too thick. If you continue to make that mistake, you'll continue to have problems. 14-15ga on the freewheel side and 14-17ga on the left side results in the most reliable wheel under heavy loads. You can use 14ga straight, 13ga, or whatever, but you'll only reduce your wheels' ability to withstand heavy loads.
12ga spokes have to be almost twice as tight as straight 14ga spokes to give equal support to the rim. That's why they cause it to crack-- the rim is not designed to take that much tension. Motorcycle rims are, but that's why they're pig heavy.
