I like my SP Elite in concept but not clear on the execution. The interior is delaminating. I stopped using the shockcord thing to tighten the waist and it hasn't gotten much worse since then.
Anyway, the SP elite as far as I can tell is patterned after an old Burley design, w/ some improvements. When it was new I definitely preferred it to my old Burley (which I only demoted because I was not convinced it was visible enough, but even the SP is not as hi-viz as it could be, although it does have a lot of reflecto on it). But then the bottom started peeling apart and now I am somewhat on the fence.
If it were half the price I'd still be happy with it at this level of durability. But it is only 2 yrs old. It was pricy enough that I want it to last more than 2 seasons, probably more than 3 seasons, before really recommending it or buying another. But I do know that, visibility aside, my old Burley will outlive this SP.
