Why some people prefer heavier blades?

I have two blades that I like and use more than others. One is 80g ALL + and the other a 95g OFF blade. I can hit and loop well with either. Both feel well balanced, transfer ball feeling, and let me make my shots with good control. The heavier one DOES feel more powerful, but you'd expect that from an OFF blade.

yea, i still don't understand why people think that fast stroke with light blade will give them power. I only felt myself cutting air but i didn't feel the ball at all when i use lighter blades. You don't get a lot of feel with lighter blades and impact at contact point.

first of all heavy blade does not mean that its weight should be near 100gm,but where the balance point is.oc is abt 87gm but not heavy since its balance point is at the middle point of the playing surface which makes it a balance combo for offencing game.
most people likes head heavy(not over all heavy) blades or combos because it imparts more pressure on the ball than the balanced combo which make the player feel the ball better.
and i must say that most of us cannot
1)transfer weight at right time(less power)
2)do not have right action(less control and feel)
3)move according to the ball or choose the right type of shot(whether to go forward or to lift up)for a ball.

using a balanced combo does not counter any of these problems but a head heavy combo can counter first two problem.

a light combo need perfect contact and timing and very fast action and not good for far away from table

so it realy lookes like
1)if ur quick on ur feet u have a choice between both type of combos
2)if ur slow u should go for a balanced combo or stay close to the table with a heavy one to kill when possible
