Not that i mind the look of the cast iron what do they weigh? The plastic does have 75 per side and keep in mind i haven't put the lighter cast on mine but the 149 has certainly come alive with what it will pull since the loaded tires and added the extra 150lbs of wheel weights! You can stack the IH ones though? right? Whats the total weight of those when that is done? I might eventually upgrade to that but not until I bust these
