I think what he means is, you have a nice rig either way. Most of us don't already own a 7' shredder. Whether you buy a bat wing or not, you have a nice rig... In fairness, when I read your original post, I got the feeling you weren't hurting for finances. (Not suggesting you are or aren't)
I mow 12-15 acres of Bahia a week with a 5' finish mower and a 20 year old 20hp tractor... It's possible that I'm short on sympathy, in comparison.
Either way bud, I hope you make the best move for you. We can't necessarily make that call.
