My arrow weight is 316 grains, I am trying those new satellite arrows...

My bow is approx set at 63 or 64 pounds..

I was shooting a 491 grain, 2315 with feathers and getting 240 ft/s with 63 ft/bs of KE..

I didnt switch anything with my setup except I dropped my weight down to the 63 to 64, it was around 66 with the SuperSlams..

Now when I put in the 316 grain arrow with my speed of 275 i get 53 ft/lbs of KE..

I did add an extra set of rubber whiskers too to help with the added noise..

I am shooting the carbons with feathers also.. They had Plastics, but the plastics made way too much NOISE.. almost sounded like they were roaring.. Kinda like if you let a piece of plastic out yoru window going 60 down the highway..

So... If I would have stayed with the exact setup i had with the aluminums, it dropped down to i believe 58-59 ftlbs...
