Went to the indoor shoot on March 7 in PA to see what the Dauntless would do. Unfortunately I did not have any properly spined arrows for it. Though the Dauntless was fast and very quiet my arrows were exhibiting erratic flight. I did bring several CE Heritage bare shafts that were cut to 29". With the standard aluminum RPS inserts intalled and 125 gr. points, all shafts showed that they were spined too heavy. I installed 145 gr points on the 90 and 150 shafts and though the 150 shaft was still too heavy the 90 shaft flew fast and true.Preferring the larger diameter shafts of the 150's I ordered the RPS weights which should arrive soon.
