I must admit I had my UCR's done for me by a chandlers, by the time I had costed the rope and a splicing needle, (I opted for 3mm Dynamic sk75 Dyneema @ 1020kg BL) and postage, it was as economical to get them to do it.
We pay rather more for specialist ropes than you guys seem too, for instance the 3mm sk75 was on offer at £1.49/metre, that's $2.46/metre, cheapest I could find, the D12 and V12 are way more costly.
They are a thing of beauty though
I cant wait to try them out on my DD.
I did however buy some additional sk75, so will be trying my hand at splicing with that.
