Sorry not helpful per your exact question but here are a couple pictures of bumpers available right now via the group buy everyone is mentioning (supposedly ends this Sunday the 15th)
plate bumper (depends on what you like, notice how nice and tucked in this one looks compared to the shrocks)
a tube style one (they are also offering a pre-runner style but I'm guessing you're not interested in that style)
If your two bumpers are hard to choose from, decide what your deciding factors could be and go from there.
- total cost (shipping included etc)
- time it will take before it's in your hands (everyone is right lead time on shrock stuff is pretty long)
- weight of the bumper
- if one of the companies you'd rather support than the other
- go with a brandname or something new/different on the block
- if you have other products you want to order from them (build a relationship)
- if you want matching products (e.g. do each of them offer front bumpers, rear bumpers, rear corners, slides, roof racks, etc)
- can you request custom options or don't you require that (e.g. would you rather have square holes for new LED style lights, do they offer that, etc)
- I always over think everything... thats why I hate shopping for this kind of stuff...
