Hi guys, I haven' t postd for while..gettin ready for fishin season. Last season I shot carbon arrows and I was less than pleased with the performance I got, don' t get me wrong I loved the speed I had, but they were just too critical with broadheads. Obviously I want to switch back to an aluminum shaft. I shoot a Mathews MQ1 at 60 pounds and a 29 inch draw length. I would like to shot relatively heavy arrow, 7 or 8 grains per inch. Do you guys have any ideas on a type of shaft and spine. Thanks alot.
