Borgeson/MM steering shaft question

I'm interesting in getting the Borgeson steering shaft with vibration reducer for my Fox to cut down on slop and get a more precise steering feel. I see Maximum Motorsports simply buys the Borgeson units and welds them. Is there any issues with just getting the shaft straight from Borgeson? Do the set screws constantly loosen up or something, making the welded shaft beneficial? I don't even think MM offers the vib reducer model in welded form.
