The KB45XL is too big/heavy for a lighter buggy, and much better suited to the larger/heavier Savage

. What kind of bashing do you plan on doing? The Savage has more ground clearance, so it can go places the buggy can't. On the other side, a buggy can perform much better on less rough surfaces than the Savage.
