For a nice tall racked buck like that I would recommend a semi-upright mount to my folks that im mounting for. I like to show off a bucks best features and a semi-upright really does a nice job. Full uprights dont look as natural to me, but thats just my opinion. I'll throw up a few pics once I get them on my photobucket...
Here we go, these werent completly finished when I snapped the photo's but you get the idea... Regular semi-upright, good clean mount. Heres my buck from 07, hes similarly shaped to yours, just a little bit smaller :d . This is the "head down aggressive" or "hooking aggressive"
Ill post this one since its different. I chose this pose because he had alot of junk on the back side of his rack and good mass on the bases. If he would have had his head up, you could not see some of the points, not typical but it fit the rack.
