This is what I use for a similar setup, and I think it would work very well for you:
AD Trad Lite (or the even better Hammerhead Trad Lite) shafts, 100 grain brass inserts, uni-bushing inserts with g-nocks, 4 x 4" 90 degree fletching, 150 grain cut on contact broadhead.
Paul Mattson of Badger Arrows who posted above would do a great job of making up the arrows for you, and he has made some just like them for my Shrews. I can't absolutely guarantee they will fly well for you, but I almost can. The AD shafts are very forgiving of spine and point weight. And both models of those shafts are very tough, especially the Hammerheads. If you don't mind spending a few dollars more on the Hammerheads, I would definitely recommend them. You would have to work to break one and will probably lose them first. Animals can break any shaft if the arrow is sticking in them after the shot, but that is a problem all of us would like to have.
