Default Arrow weight vs Arrow speed

Hi Gents,

I want to just clear something up in my mind, and maybe for others as well.
I have read alot of information where heavier arrows are supposedly better hunting arrows....why? I understand that the higher ft/lbs energy arrow will be the better for hunting purposes....not so? In my mind a faster, therefore flatter trajectory arrow, should give better penetration,due to its straighter flight at point of impact with target. (ok this is assuming the shot is across level ground at a broadsde animal)
Now see this comparison I have done with one of my setups:
Mathews Drenalin bow, 27inch draw length, 69# draw weight, 398gn arrow

398gn arrow - 62.3ft/lbs energy 265 ft/sec speed
428gn arrow - 62 ft/lbs energy 255 ft/sec speed
500gn arrow - 59.5ft/lbs energy 231 ft/sec speed

Its evident that due to the speed loss, the energy is also reduced. There are other factors, like broadhead type, which may affect arrow flight at hgher speeds, which will make heavier arrows a better option. I use Piston Points which give me excellent flight....also remember that at 27inch drawlength, I opt for lighter arrows for better speed.

Please let me have your views,

Thanks,
