2013 GMC Sierra SLT crew 6 . 2 , gets ok mileage but is a ton of fun in summer and winter <| sep |> More like it redirects it along the path of the rail . You ' ll need to be going at one he ' ll of a speed to bounce off it , given that the spinners will just gently spin you along . I ' d expect it to be less rebound into traffic than a typical barrier , but it would be interesting to see hard evidence . <| sep |> Use more water , 150 ml is not much . I use about 3 , 5 dl for 3550 g whey . Maybe try drinking with a straw ? Drinking it with Skim Milk for already 3 months now but everyone tells me to drink it with water or i ' ll get fat . That entirely depends on your total caloric intake . I wouldn ' t be too worried about skim milk . Sometime protein shakes just taste like shit . Drink it and move on .
