Mears forms are available through McKenzie and Mears. I've heard the McKenzie Mears are different compared to the Mears that come direct from Mears (hope that makes sense!). Do you have a preference for which Mears?I agree with Robin Hood.....the Mckenzie 6900 series and the Mears forms are generally my go to forms as well. If I had to pick one of the two, I think Mears would get the nod, but that's just me.
If it's a big frame I may do ears forward but generally opt for ears slightly back. A semi sneak with a slight turn one way or another generally depending on a look I remember during the hunt. Wall pedestals are a good choice with a hard turn if there's some characteristic you're trying to show off such as heavy mass or abnormal points. Remember, some full uprights take up a lot of wall space height wise depending on how tall the rack is and the form you choose....and just my personal opinion "most" of the full upright mounts I've seen don't look natural nor do they look that great to me. However, that's just my opinion.
