Learn me about ropes

My wake rope is too short and not so smooth going thru my fingers if the driver circles around too fast, I have learned to put it on the end of my board for friction and that helps but I really just need a better quality rope that is the right length

So 12 strand or 24 strand Dyneema??? what is this?? I have used a rope that wasn't coated with plastic but was very smooth on the hands, is this the 24strand??It had a much tighter outer weave than my current rope which seems like regular static kernmantle rope by Straightline my bro got me for about $75 with handle

Also are these better than the coated ropes??

I probably will go with a new handle to, so for a beg to intermediate rider at about 70-75' whats a good rope/handle combo out there, or if nothing else whats a good quality rope to use for years to come.

For reference I don't plan on using a ropewinder and go about once a week April thru November.

Thanks
