First you can also offset the quickspins. But dont use the original quickspins they suck. I use the Quickspin ST which hold up very well. I have my quickspins offset to 4 Degrees to the right which is the max for them, that you can offset I have found that on the loger shoots they stabilize fixed blades better this is with a 4 inch vane as well. I have to use them for the weight for my arrows. I shoot a very light arrow 352 grains. But I have put don and always have passed through on every deer I have shoot even kansas deer. They are expensive to.
