I'ld have to agree with Blud when talking about wood from the today's plantations... Those trees are being cultivated much too fast wich will give you wood with an open grain and a light weight.
However, if you can someday purchase teak (preferably Asian) from before they started the big plantations, that was around 1973 if I'm not mistaken, it will give the cue a very solid and hard hit.
I had some wich was over 50 years old, because here in the netherlands, a lot of Indonesian people have been living here since WW II. Many old furniture pieces have since been thrown away...
That wood was brighter in shine, but darker in color, with small grain and the weight was around the same as cocobolo. The hit was too...
So if you have old teak, my answer would be "yes, it's good wood for cues". If not, my answer is "no..."
TIP: Teak is a specie of wood wich finishes bad, because the wood contains a lot of oil. Try to build up a smooth surface with thin epoxy based sealer before starting to finish it...
