The real key to whether 165 would be good for you is how much your knee bend is on your back-stoke. You want you knee bend to be about 90 or more. Anything less is ultimately bad for you knees, and your power making ability. When you knees are bend more than 90 degrees you cannot really make good power until they open up to that point - which will only happen as you continue pedaling - but when that point is reached you have lost a significant percentage of that "10-2" range where you make most of it. Not to mention your knees hurt if you try and push hard when compressed at more than 90 degrees. Hope this helps.
