Get the picatinny. High or low is personal preference.
It gives you more flexibility in scope eye relief.
It just looks a whole lot better than the old school mount.
Even without the scope on it, I think it gives the rifle a nice scout type of look.
The last benefit I recently realized after 5 years of using it. I've never found any shell marks on my scopes although I do see brass marks on the bottom of the basset. I think it defects them away from hitting the scope. So I see that as a major plus for the pic mount.
I have 2 of the high pic mounts.
