I’ve been running rip tkos for years the standard outsert is the weak link of the arrows other wise super tough difference in 250 spine and 300 is 0.1 gpi so going up a spine won’t penalize you in weight. I switched it up to a super lightweight HLR with titanium up front for a total weight of 377 shooting my phase 4 33 75# at 30” shooting 332fps it absolutely rips and is very durable. I would not hesitate to run the rip tko but don’t go with standard aluminum outsert they don’t stay straight for long.
