The poundage of my Bow is set at 65lbs. due to the draw cycle being so smooth and easy. I used the PSE X Weave Carbon Arrows with My 9 year old Matthews FX and they shot very well at 55 lb. draw weight. The number on them was 300, but the guy at Bass Pro said they were to stiff and recomended the X Weave 200,but I think they are to light. I prefer K. E. over speed so this is why I'm asking these questions to see if anyone else has this same BOW. I have very short arms and my arrows are therefore very short they are 25 1/4" long with the Blazzer Vanes. In the past I have always used 100gr. Grim Reapers and was think of going up to 125gr. this year with the 300 arrows to get a little more Kenetic Energy. Any good advice is gladly received on this possible change.
