Yeh , Silent .........with your 80# or more of KE .........I think those tips will help with penetration !! Instead of just reaching the earth's core after a passthrough...........you might actually make it to China !! [:-]
I shot a 60# pig last week with my 80# ke set up with an Axis and a Spitfire and lost my arrow in a mudhole after a passthrough..........it should've hit China Thursday about dinner time !!!
Serously.......I think the original tip would be better on bone.........but unless you have some weak KE..........I can't see there being a big difference !!!
