Hi Guys, just looking at purchasing some rope to go abseiling once again, 
great stress relief after a hard days work, which rope should I get, static 
or dynamic and which size, 11 mmm or bigger?

Also, isn't it the rule of thumb, the bigger the figure 8 the faster  it 
goes or is it the other way round?

If it's just for abseiling, get static. 11mm is ample.

Generally yes, because the smaller the fig8 the tighter the bends, so 
higher friction.

I do have a ladder rack here but I find if I use just 3 rungs its too fast 
but with 5 its too slow

An 11mm or 13mm Static line would be best for abseiling activities. A 
dynamic line would promote "bounce" in the rope and for the money you 
would spend on it, you wouldn't get the life out of it.

A note that figure "8" devices cause the core of the rope to "twist", 
making the curly pig tail things in your rope that are really annoying!

  - On a dynamic rope this can cause reductions in the elongation 
(stretch) of the rope. This happens because the twisting effect will 
undo the designed twists of the strands in the core of the rope which 
give it the stretch properties.

Your rappel rack will save your rope from the dreaded twist (its an 
in-line device and doesn't bend the rope for friction). On a 13mm line 
you will go slower on three bars than you would on an 11mm.
