i also just made a straight shaft for my excalII. i got my 7/8 alum. shaft at west marine is was six foot long, so i had to trim it down. I used a mountain bike climbing bars for my handle. i took my arm cuff off of my factory s shaft. i set the controller at the end of the shaft, as to give the coil a counter weight. it took soome adjust of the placement of the arm cuff and handle to be balanced perfect. if the balance is not right, you might as well keep your s shaft. i will post a pic of mine. i went and field tested it for 2 hours at the beach and loved it. I made the shaft length longer as to give me more ground coverage per swing, the only thing is you have to slow down your swing and walk because of the coverage. I also added a 2inch wide strap to the arm cuff, which really locks you the unit.pretty happy with it for now!
