Which Kuat rack?

[torquer]

CC emailed that their 20% off promotion ends today, so I need to decide which rack to buy. Between the Sherpa, NV and the NV 2.0, what am I getting for the extra money? We'll only be hauling two road bikes, so no need for an add-on. Lighter weight of the Sherpa reinforces my natural inclination to spend less. Do I give up anything else?

Edit: just checked CC's site, and the NV is gone, and only NV 2.0 for 2" receiver is available. (We've got a 1.25" hitch, so no adapter option for us.)
So I'll go with the Sherpa, unless somebody makes a compelling argument for me to either spend even less on the Transfer (a rare argument in these parts) or hold out for the 1.25" compatible NV 2.0. (REI could be an option for that, but even with their 10% rebate and no-charge shipping to their local store, I'm still paying sales tax, so basically list price.)
