RE: broadhead tuning question
Don't switch to mechanicals when things aren't right with your setup, it'll just create different problems. The Gold Tip website doesn't list any data for those arrows but the spine seems on the light side, so try cranking the bow down to 60# and then try to retune with the slick tricks. Another problem could be with your FOC, 8% is the lowest recomended amount and many go with greater than 15%.If you up the FOC your arrows will definately be too light, see if you can't borrow some heavier spined arrows from a friend. Another thing that you could try is to switch to another fletching. Blazers aren't for every setup, I switched to 3" quickspins and my broadhead flight improved.
