LOL, yes most ropes come covered in wax. Not sure what the purpose is but the more you use it, the faster the wax wears off. As for the stiffness, there is not a whole lot you can do to make it more supple. Do you remember what the lay was on the rope when you bought it? I've seen them range from H (hard) to XXS (xtra xtra soft) and SS (super soft).
I'm not sure what you are planning to do with it, whether it will just be a practice rope, maybe you are doing some ranch work, or are wanting to get into team roping or breakaway roping, but that will all influence what kind of rope you want.
Personally, I do quite a bit of ranch type work from roping 1000 lb momma cows to baby calves and I have found my favorite rope is the XS Hypnotic by Cactus
. The diameter is small enough and it is light weight enough to be comfortable for me. The XS lay gives great flexibility and suppleness to get it underneath those babies that are close to the ground but, being a 4 strand, still has the strength to hold the big ones. The only drawback is that it is only 31' long and doesn't offer a ton of reach on the range.
