Thanks for the suggestions. I ended up ordering a new RBV72-HF33-O. I rented the IRC 72, and it was a beast, but I think a bit heavy for my CAT 246D3. After a lot of discussion with my CAT dealer and Virnig themselves, they bid a nice price on the V50, and I went for it. The strategy to rent and try one out paid off, and I must say Virnig and my CAT dealer were great to deal with. Each time I called Virnig sales, they were great, and spent a lot of time discussing my application objectively. Virnig is not cheap, but service and support is worth something. My conclusion is that you get what you pay for here. It will arrive in May, which should leave me with a good summertime activity of pasture clearing.
