Ive been shooting RIP TKOs for a few years now, and been pretty impressed with durability. My arrow build is fairly spendy but they really dont break. I went with the RIP TKO because im a long draw length shooting heavy poundage... which makes it hard to find arrows that are not ridiculously heavy. I shoot the Iron will inserts/collars on a 200 spine... after shooting steel framing in 3d targets and plenty of dirt i have been surprised with how unbreakable they are, especially considering that im shooting 640 grn TAW at 282 FPS. Its maybe comparing apples to oranges here due to the differences in our spines and overall setups, but I think the weave does make a difference for strength, so looking for a lighter GPI may not be a bad idea with the HLR... i just dont have experience with them since the weight difference isnt significant at a 200 spine for me.
When i first built the arrow and shot it for the first time, i shot a bag target in the garage leaned up against the bow press and had the arrow blow through the bag and hit the square steel tube of the press on the other side... made a hole in the pipe and the arrow was perfectly fine. didnt bend the insert, or damage carbon. Just barely rounded the point on the field tip (easton 125 grn ballistic tip). Long story short, I dont think you could go wrong with a RIP TKO, they are pretty much the best strength to weight ratio that Ive seen. Im always looking to shave weight off of GPI, so that I can use a heavier insert up front for FOC and still maintain my arrow speed (while still being correctly spined)
Theres my 2 cents haha
