Should i use the ten finger grip when playing golf?

I think someone asked a question like this before, but i want to know if there are any disadvantages to using the ten finger grip. So i started taking lessons about a year or two ago. I can hit pretty far with my 7-iron, about 100 yards or more. So i used to ten finger grip because my teacher told me too. I used to use the over lapping grip. After switching to the ten finger grip i hit the ball higher and farther. My mom's friend (he loves to play golf and spends a lot of time at different courses) asked me how i hold the grip and he said i should use the overlap or interlocking grip. For some reason i find it hard to use them. Should i use the ten finger grip? What are the disadvantages and advagtages? Oh yeah....i place my club a few inches behind the ball and kinda of "pop" out my wrist before i hit the ball if anyone knows what i mean. that's what my instructor told me a few weeks after switching my grip. My mom says i have a lot of strength to hit the ball far, my teacher too.
