Your green alright,,
Without getting into the age olde discussions about what's best, because it's really a matter of opinion, needs and experiance, I actually think you'll "learn" more with the Dixie kit. If I was the instructor the first thing I'd have you do is re-shape the buttstock to Historic dimentions then re-inlet the patch box and butt plate. With either one ALOT of wood needs too come off to actually get the right shapes, they leave the stocks bulky from the factory and nothing looks worse than someone that simply sands the wood down then slaps stain and varnish on'm. I'd have'm solder the rail and fully dis-assemble, polish and fit the lock and trigger parts, (from a paper bag full of loose parts), then add a side plate and ramrod entry pipe.
If you want a gun that's shorter that's the one. If you want one thats actually more like a Hawken and capable of being shaped more historicaly like a Hawken the GPR is the one to go for.
The GPR is a fine gun and will come highly recomended by many. The need for conicals is in and of itself a rookie desire unless your going for Elk or Moose. 1-48 twists are faster and will shoot conicals better, but the Round ball is more than enough for Deer/BlackBear size game. The 1-48 can shoot ball well also, it's just a matter of working up a proper load.
