I believe you have made a good choice. He can likely wear the plain, three-tassel for many years to come as it is essentially a timeless style. He has to carry very little, actually, so the size is not an issue. He doesn't even have much of a wallet at this point, so maybe he'll learn to carry less. I've gone from a suitcase-sized Rob Roy to a much smaller, hunting style. I just don't carry so much any more.

And besides, that's why God invented pockets in shirts and jackets.
