I don't have an issue with either feathers or Blazers. I've used both and currently using Blazers. I would even contemplate using feathers again, especially with my drop aways.

You can go to an extreme helical or offset with your feathers and a drop away for optimal arrow/broadhead flight. I am however getting this with my Blazers too. The only difference, the with high profile Blazers, there are at times other clearance issues.

Both have their place in the archery industry, both work extremely well and it comes down to personal preference.
