Any opinions or ideas for alternative protective gear, specifically shoulder/chest protectors. I am looking to test the waters of downhill mountain biking this summer after mainly riding XC and All Mountain. Living on a relatively tight budget I don't want to spend money on all the protective gear if I'm not really going to use it all that much. I'm looking at used gear and thought maybe hard-shell lacrosse pads might be a good alternative to conventional MTB pads (they tend to be more common used in my area from what i've seen).

Renting is also a possibility but only if i'm at the resorts. Just looking for input, and seeing if anyone has tried this.
