I love my black GGII!
They're cheap, straighter and more consistent in spine than affordable carbons and in my opinion just as tough!
When fine-tuning you can use hotglue and heat the shaft as often as you want.
Also I can shot my favorite nocks (Bohning classics) and don't have to pay a fortune for those tiny carbon nocks where you can't even feel the indicator!
I use pieces of brass rod fo frontloading and getting FOC up.
There are no field points heavier than 125 gr. here in Germany.
My GG have an all in all front weight of 210 grain and a FOC about 18.
