i've been planning on buying one but this 20% off thing that scott mentioned has moved up the schedule. is there anywhere besides the lifeline website that i can see a better description of the various jackets. i like the looks of the #160 and #170 but not sure of the difference. i'm just lake/river riding at speeds in the 90's, hopefully a little more in the near future. don't really want to go to the full race version. it's a little bulky for cruising. thanks
