If you really think they end up in the same place, I would normally redshirt the 54 WE guy. The 80 WE guy will improve enough in his first 2 years to give you 2 good years without a RS, while the 54 WE guy might need the RS plus 2 years to be ready to give you starter-quality performance. In this case, however, I agree with the guys who say the 80 WE guy. Since you have a 6-man class, you're going to look to go deep in the tournament the senior year for this class. With a RS and 2 years, the 80 WE guy will have developed about as much as the 54 WE guy in 3 years, and both may be close to capping out. That gives you the best 5-senior team possible, so given your circumstances that's probably your best option.
