Since one is based on the other, I'd assume they have similar attributes. I'd like to hear from those in the know about Wright products. What are the pros/cons of the two types compared to each other? Since I always prefer to sit rather than stand I'd lean towards the Sentar version unless there's something I haven't considered. I don't do many big hills but it's never bad to be able to in a pinch. I'd be using it on flat to rolling small and medium Bermudagrass lawns, and a few gated Fescue back lawns. I'd be mulching. Any reason to go with the stander version instead of the Sentar? They've even very close in price. The wb/sulky thing makes my back tighten up from leaning forward. They're fine on small patches, but day in, day out, I'd rather save as much energy and fatigue as possible. I keep wanting to buy a Stander and this small Sentar is the first design that seems to have what I need.
