I will be curious to see if you can tell a difference between the two wings, either in speed or in handling. According to the Xfoil run, the 8.5% tip wing will be more prone to tip stall and not all that much lower drag. But that's just a 2D simulation and I don't always believe simulations.

The 700,000 Rn is roughly 160 mph and the 220,000 Rn is roughly 50 mph (landing)
