Braided ropes weigh like we're braiding docklines and weigh 20 or 30 times what a storebought rope weighs. Storebought heavy rope weighs 3 stone.

Could heavy ropes be added to stores in Mer'kresh, Hara'jaal, Ratha and Muspar'i? All 4 are geographically removed from the nearest shop that sells ropes. Mer'kresh and Muspar'i in particular have very few athletics training locations available so B&E becomes the only dependable trainer. Currently (afaik) the only places you can buy a heavy rope are Crossing, Hibarnhvidar and Aesry.

Alternatively, (or maybe in addition to) could braided rope weight become more comparable to storebought?
