Thanks for the replies guys! I figured out after looking at some 100 and 125 grn field tips last night that these must be 150's. I'm going to see how it shoots with 125's tonight on the factory firebolt arrows, planning on going with 2 blade rage broadheads (125 grn). Let me know if guys have found a good arrow/broadhead combo for the phoenix as this is my first crossbow and first hunting season with it.
