Stick with the 170's, wont make a blind bit of difference going to 165 or using the 170's other than to your wallet.

I agree with sheffsimon, stick with the 170s for now until your body tells you otherwise. You could also read this excellent article, which shows that a lot of science could be applied before it all boils down to a subjective decision any way:

There are quite a few other threads on crank length that make interesting reading but seem to draw the same conclusion.

Im 6ft and ride a 165 on my single speed and 172.5 on my road bikes, and I dont worry about it.

If you are worried then go for a bike which will give you the info to set your bike up properly.

I'm also about 5ft 6" with 28" inseam leg.
I had lots of trouble with pain in my hip, right thigh and knee when using 170 cranks so switched to 165. It was the best thing i ever did. No pain at all now.
Unless you having any similar problems, stick with 170 and save your cash.
