Guess my point was... for just riding the weight really doesn't matter. I would never want to race with my tank, and agreed that the acceleration of the lightweight is way better. Just the light weight wheel set probably makes the biggest difference. It also seems faster since I'm in a much more aerodynamic position instead of the upright grandpa posture on the Surly. So drilling out your tire levers is pointless, unless it makes you feel faster.
I was a USCF CAT I/II racer in the late 70s, so I have some experience in road racing. The heavy bike has no jump, but the ride of the big bike on crappy roads is nice.
I'll still ride the race bike when I want to go out and be a stretchy suit commando, but for just going for a ride the tank is just as fast.
A few weeks ago I came to an intersection an found myself in the middle of a bike race. My competitive gene kicked in and I passed 8 or 9 fat guys on carbon bikes. I got some great looks as this guy on an LHT with racks and fenders blew past. Fortunately I turned off in a few miles, totally spent and feeling like I was going to puke. Unfortunately I still had 40 miles to go to get home. Then I hurt for the next week.. but it was fun.
It's all fun.
