Cable/Tentacle roller tools?

I found 4 different ones sofar: http://20mmandthensome.blogspot.nl/2015/03/a-bird-on-wire-cable.html

But now I'm wondering, transparant or black? Does it matter? What is easier? Do you use one and how do you feel about it? (and why are they so damn expensive!)

Interesting thingy. Have no clue about what would work best, but like the possibilites!

I have a set of the original Masq Mini resin plates, before they did their current version. They're not too bad, but take a bit of care, finessing, and otherwise getting used to their foibles. Part of that is getting the ribs to line up, though pushing the horizontal plates up against a vertical surface (like the side of a box or block of wood etc. etc.) helps. And I'd still like an even finer set of ribs, too!
Maybe it'd be better if they were transparent, I dunno. Seems to me it'd be like trying to look through a bathroom window, with all those ridges, and you'd end up guessing and peering at the edges anyway.

Let the epoxy putty firm up a little too. Makes it easier to roll the initial cylinder or tube into an even, round shape, then lets you manipulate the thin tube without squashing it too much or leaving fingerprints, and press the plate ridges into the putty without cutting right through it too easily.

Also handy for using up little scraps of leftover putty from other parts or projects, if you've got a few minutes afterwards. Build up a wee stock of potentially useful bits.

I have the the three old opaque ones from green stuff industries.  They have a back plate to line up the two surfaces.  Their new ones are only in clear resin so that might be another option for you depending on location.  http://www.greenstuffindustries.com/store/p1/Tentacle_Maker_Tool_Box_v2.html I have used them on several projects to great effect.  Just like Vermls said it takes some getting use to and letting the putty firm up helps greatly.  Another comment that I have is not to use water based putties lime milliput/epoxysculpt/magicsculpt becasue if they dry on the surface it is murder to clean.  Hope that helps.
