Sticking to your original question, I would buy the Woodsman if it has double set triggers. Aside from other differences, the set triggers indicate that it has the better quality Traditions lock with a bridle to better support the internal parts. The Kentucky model, although not a bad little rifle, carries the lower quality lock without an internal bridle.
Just to confuse things a little more, you might also consider the Lyman Trade Rifle. Similar in appearance to the Woodsman, and available in .54 cal., it is a high quality rifle, bridled lock in spite of being single trigger (which I actually like better for hunting) and is priced significantly less than the GPR. Can be purchased online for very reasonable price at Midsouth Shooters Supply, D&R Sports in Pa., or other similar. I have both and use the GPR, with its longer barrel, mostly for paper punching and occasional hunting. Woodsman, GPR or Trade Rifle, enjoy shooting!
