Looking hot is great and all, but no one knows you have a six pack under that shirt, and they likely won't look twice unless they can see some lumps (Chest, arms, back), through the shirt to get thier attention. If you insist on keeping a chiseled six pack, you will have a really tough time gaining any signifigant size. Get big, THEN worry about abs. Trust me, I have lived it.
If abs make you feel good about yourself, and you don't care about what girls or other people think, then just ignore what I said. What's important is how you feel. Personally, a ton of strength, and big ripped body make me feel like a million bucks. When I am happy, I treat others better. This is important.
