also on the subject of stopping my feet scrubbing and hitting frame, if I do that I feel like I push my heel out. Look at my stance
Found 165mm 50 34 as well
Yes, your getting conflicting advice left right and centre here.
Personally I would like to isolate one issue at a time and work through them first.
I think your leg angles are too closed up (your knee is getting too high at the top and not particularly straight at the bottom) and lowering the saddle will make it worse yet others are claiming that your saddle is currently too high.
What the shorter cranks will do is to allow your leg angles to open up while the saddle is in a relatively lower position.
I'm guessing that you have asymmetrical issues with your legs that are making things worse.
