Go to Gander Mountain and get a pair of the polar fleece long underwear to get you started. A good set of gortex boots will also keep you warmer and dry. I too have very poor circulation in my hands and after 7 years of working outside through the winter have figured it out. The hand warmer packets are your best friends. I usually wear a long sleeve shirt, a tall neck zip up polar fleece and then a good thick hooded sweatshirt on top. Menards sells gloves with short fingers that are cut off and a mitten attachment that you can pull over the top and the same for your thumb. Get your hand warmer packets out on your way to the course and put them on the defroster of your car. Those packets get started and warm much faster that way. Drop a hand warmer packet in the backhand of your left glove and one in your hoody pocket. When you aren't throwing keep your right hand glued to that hand warmer packet in your pocket, and when it is really cold throw your right glove on with another packet in there. It's only a buck for a pack of the warmers and in my opinion that is cheap to stay warm. I also try to take the warmer out of my pocket and shake it every couple of holes, it keeps the packet warmer. I hope this helps.
