My experience with the Heavy Hitters is they are a bit weaker than the standard GT shafts with the same spine rating. I've also run the shafts through Stu Millers calculator and he shows the dynamic spine of the HH shaft to be about 3-5% weaker than the same rated regular GT shaft. My comparison was with a 3555 'standard' shaft and the same spine HH with an overall length of 29".
If you like the mass weight of the HH, you might also consider playing a bit with overall length. For example, if I go a half inch longer in length, the dynamic spine of my set up goes down 6-7%. Most setups can go longer with no problem. Shorter is a different issue. So you have an option to go along with changing point weight.
But be aware going with the HH you will see a velocity drop of around 15% compared to a standard GT with all the same point weight, etc. I'm not advocating speed, just saying there are always tradeoffs.
When you absolutely have to have a heavier arrow, the HH is the easy way to get it vs. weight tubes and other options with the standard shaft.
I think the point BigJim is making is you will have a wider range of options and likely get better overall performance with the standard Gold Tips vs. the HH option given the draw weights you are working with. As usual, BigJim is right.
