You don't want 5" feathers with light arrows(yours are considered light).They will become unstable at distance(reason is you can't slow a fast arrow down too fast or it becomes unstable) and your groups will open up.At HIGH speeds and light arrows,less is more.BUT,imo,I like 4" feathers for hunting with fixed blade broadheads.Even 4" feathers will adversely affect your groups at LONG range.



Those axles need some attention,no way should they stick out like that.There are spacers missing,get to your shop and get it fixed.That could be your noise,too much moving around up there and this will also make the bow less accurate.
