I bought six Safaris a couple of weeks ago. Two spined CONSIDERABLY higher than the other four.
The stumpshooters tend to have ID/OD issues (sloppy nocks/inserts), and scuffs. If you have a variety of heads and some screw in brass adapter weights and the time to individually tune each arrow to its optimum, you'll be hard pressed to find a better roving arrow. You will have to enjoy tinkering and be patient to get the most out of it.
When tuned they fly great, and are difficult to wreck. Start with a three pack of Alaskans and see what you think.
