Both have good, valid, points. It is all about whether you want drum corps to be big and popular or if you like it cozy.(IMO) I don't know how he would feel, but i think the best job on earth for George Hopkins would be with BOA or a very similar organization, or perhaps a larger part of DCI. He's all about sharing the wealth. Everybody's a part. Not a bad thing, but not necessarily what drum corps is/needs. Music education in general needs someone like him.
Scott Stewart on the other hand, Is all about taking the kids and showing them a good time and making them better people through what HE knows. He's not concerned with how many kids he teaches, he just wants to let those who may be similar-minded, have the experience of a lifetime. He's perfect to be a corps director, but I wouldn't place him in a higher position. Drum corps need someone like him, to give those who think like him, a place to go.
Just my opinion.
