I sold my Mission MBX 320 and upgraded to the Horton Storm last September. The Horton is very heavy and I find it extremely unwealdy much more than other Crossbows I've owned. It's very accurate but quite loud. I may get rid of it and go back to a Mission, which I could shoot standing, sitting and kneeling. With the Horton I have no choice I have to sit. Does anyone have the same problems, I was attracted to the A to A of the Horton but the weight is extreme. The excalibur are light but very wide , I believe the Missions are the answer.
