Some thoughts: the dynamic spine of the 3DHV remains fairly constant with point weight changes due to the longer shank inside the shaft with heavier points. I have tested this with bare shafts off a recurve. 150gn weakest, then 100gn, then 120. The dynamic spine difference between 100 and 120 was minuscule and still small with the 150. Small enough not to matter a damn with a compound. Considering the smaller diameter and longer shanks with the VAP, I would bet that they run dynamically stiffer with more point weight. You’ll speed those VAPs up a bunch by dropping to 100-110-120gn up front and thy will shoot just as well. Dropping to 100gn will give you back 13-14fps right there and the bow will feel crisper. Seeing as the 3DHV are 400 and the VAPs 350, I would bet the 3DHV are running even weaker still due to the much, much shorter 80gn point combined with the weaker static spine. I’d put 100gn in those 3DHV to get the required 5gpp...
I liked the side by side comparison. Good data. Also I will rethink my point weight of my 3D arrows to make them lighter if I can still spine my arrows for good flight with a lighter point weight.
What was the relative humidity? Love Your work Steve, but You leave out so many varitable facts! Hahaha, that Bow looks Da sheee, great review as always, thanks AS.
267 grain divided by 60 lbs thats 4.5 grains per pound. Thats like living on the edge for those bow limbs. Not sure how low u can go before it starts to behave like a dryfire of the bow itself ?
This was my thought. I am trying to set up a dozen 3DHV for my 60lb 3D bow, I am really struggling to get them spined but keeping the 5GPP. I don't dare go that light
I calculate the 3dhv at around 283gn based on experience of them coming in about 0.1gn heavy, plus the bushings etc. Still just under 5gpp. At a 28.5” draw, I’d cut another inch off them and stick 100gn points in. Would give a 300gn arrow for smack on 5gpp.
First off you should be using 350 spine according to the spine chart and your bow specs. Secondly that arrow is too light for your bow poundage. You need minimum or 5grsins per pound of bow your shooting so your minimum weight should be 300 grains at 60lbs. I calculate your arrows are 280 grains- way too light!
This was about the most un-useable information I’ve ever seen. What’s the point? One arrow 400 spine with a 90 grain point. One arrow with a 350 spine and a 140 grain point. Then you talk about how much faster one arrow is than the other one.? Made no sense. Point weight, arrow spine , arrow length, arrow diameter or bone of this matters when it comes to speed test on an arrow. Arrow weight is arrow weight, and at point blank range, the total arrow weight determines the speed. Build a150 spine arrow with a 150 grain point at 30” long that weigh 400 grains, and then build a 500 spine arrow with an 80 grain point that’s 26” long but weighs the same 400 grains. You get the same same fps through the same bow and chrono. Again, this just wasn’t informative or helpful to anyone. In fact, misleading and completely wrong

What the PSE engineer was basically talking bout is called "lock time" as it is commonly referred to in firearms.
The 3dhv had a 80grain tip and 400spine, the vap had a 140grain tip and 350spine, not really an apple to Apple test obviously the 3dhv is faster._.
Is the 3DHV still within the 5gn/lbs limit? A weight comparison between the Goldtip and the 3DHV would be very helpful.

Nice! What's the mass weight of the 3 arrows?
Ahahahhaaa!
Marla probably wonders why Steven Hann stands out in the yard talking to that lil' camera all the time?🐩🤔
Ok so how much $ 🤘😎
Hahaha, Tell Em the price Son!

This comparison is bullshit! Do it whit same lenght, same spine, same point.... Thats would be a real comparison! 😉
