Had thought this thread had died, but just noticed the activity.
First I don't have the LHT, but the CC (not sure if that is relevant) - and I have checked my saddle position. It is somewhere in the middle right now, but I did the plumb line thing and my knee is just ahead of the neutral position. So I don't want to push my saddle too much further forward (I could try it and see if it causes problems).
I do have a riser stem currently, but maybe I can find one that rises at an even sharper angle.
And finally, I agree with MC that the 42 bars may make the difference. I mean at this point I'm not sure where exactly the discomfort is coming from (too far or too wide?) - all I know is that after about 5-10 mins on the hoods I default to riding on the tops because it just feels better.
Anyway, I hate the look of the flared bars, and I can't really go wrong with 42's (since that is the recommended size based on my shoulder width), so I may just do it and hope that is improves the fit!
Thanks all for your inputs.
