Pictures??
A pretty frame is much faster than a less elegant one.
Not sure how oversized your tubing is.
The really skinny steel frames are a little more eye worthy that the bigger diameter tubes(but just a little)
Elegant looks are worth the weight penalty if you don't race.
CF frames-rarely elegant looking-
If you aren't racing,and like your frame-it's elegance should trump 2-3 lbs
But we need a picture to pass judgement on whether its looks make up the 2-3 lbs.
