DAYAM!!! GO BACK TO SCHOOL DUDE!!! SJ21: so you are saying that because the h22 is twice as big, its twice as heavy right? Well thats all gravy... 2.2 - 1.6 = 0.6 so by your own method (wich is probably inacurate) the h22 would way less than 1/3 more than the b series. wich as dubster pointed out is aound 75 lbs!
