burniestarted the thread to discuss why you would use 85 gr tips. We stated why and why we disagree with it. That's not hijacking a thread.

As far as a rainbow shot you must not have shot a lot of bows to know that simply isn't true at normal archery ranges. My arrows did not rainbow at normal kill ranges that's all that matters. You are the one that stated "Compounds are highly efficient machines."

And, if 400 gr arrow gives you more KE why not use it when you have a light set-up? Also, there is more than just KE that matters, penetration and momentum.

And one last thing, you have to make sure it's a well placed shot or it will be a very poor shot. Why not give yourself a better chance on a misplaced shot?

Listen, I'm the last one to tell anyone they need to use a 500+ gr arrow and never stated you should. I'm simply stating that people overestimate how great today's low poundage bows are and if they are going to compare them to bows from 20 yrs ago that were 20 lb heavier in DW they need to realize that we used much heavier arrows with the slower bows. Therefore, unless you are going to use the same arrows you can not call them equal.
