Great responses thanks! It's been a long time since I put time in on the Arione, but I must have moved on from the only one I ever had for a reason...I just can't remember why. They are easy to find though so I'll see about picking one up again.
Will also see about getting some time using the Power. I know my sit bone width so hopefully that will help in getting the right size.
In the meantime I came across a good deal on the Astute Sky Line and its been an instant improvement but time will tell, and I'm willing to try what you've recommended too. Thanks!
