Well the the boys in Iowa sent me a doz. of the new HT1's for my bear hunt. These arrows are amazing!! 14/64 od, solid constuction, 9.1gr per inch and a +/- .001" straightness. Fully dressed they weigh in at 477gr!! Heavy weight and small diameter equals serious penetration and minimal wind drift. They will be available around mid summer. Stop by your dealer check them out!!
