I wish I had stuck with rip tko’s instead of investing in hlr’s this year. I’ve broken 3 rip tko’s in past five years, one without explanation, just took it out of the target and it fell in half. Two cracked at the back after being robinhooded several times. And these two I just cut and refletched. By contrast, there’s hardly a day I don’t come back from the range without a broken HLR. I now have a whole system of how to deal with broken HLR’s: I cut them 29 inches and use a HIT and iron will collar (470 grains). When they break, I cut them to 28”, refletch, and use a much shorter podium collar (~440 grains taw). When I’m done breaking and shortening the hlr 29’s I’ll switch to 28’s. Also, I’m now using nock collars to protect the shafts. I bought the hlr hoping to reduce arrow weight, but with the front and nock collars and the extra length to keep the collar from hitting the rest, I end up with an arrow that weighs more or less the same.
For what it’s worth, I found my hlr’s fly snd tune well with 17% foc, and the rip tko’s with 13% foc. Achieving the higher foc also added weight to the hlr. I know others have had different experiences.
The lesson is add up the weight of all the components and factor in the additional length and weight of the shaft if you go with collars.
