stainless steel vs aluminized steel, mandrel bent vs regular bent

what size pipe is that? looks good the second time around, can't say that about the first attempt! if it is 2 1/2 inch pipe then get the guy to heat the bend around the axel and get it cherry red then he will be able to bend it over or up a little to clear the axle. i have had to do this in the past as well. springs as you say also will help if it is sagging some too! looks like a great system. so how do you like it? how does it sound? do you see or feel any gains from what you had on it before?
