Ooh, heavy bats, my specialist subject.
If you are going for a Tendulkar style profile, you need to accept that it will, more or less, pick up its weight come what may - the only similar thing I've seen that doesn;t is a modified Hattori that Matt made me last year, which maybe comes in an ounce light in feel. If you want to feel like you haven't got a 3lb-ER, you need a higher spine, which elongates the middle and seems to give a knife like pick up (M&H Distinction and H4L Tempo in my possession both feature this) or look for a light weight cleft - which usually means one that is not so cosmetically sppealing (I have a 3lb Powerbow Extreme that doesn't feel anything of the sort).
