Agreed, 5.4 grains per pound on the top of the line bows means nothing as far as wear and tear on these bows, strings or cables. The last 10 years I've shot right at 5 grains per pounds on certain bows, never once blowing a single piece on my bows.

This particular setup is pushing 80 ft lbs of KE as well....the bow is super quiet, no shock, vibration etc....

Sorry David, in the past it might have been pushing the envelope, today, these bows are more than handling the situation.

My speed is real life as he requested, my arrow weighs in 19 grains under what he requested.
