Most of us thought the Pettitors were an improved iteration of the Obsethed, learning from that earlier Seth ski. But not all: it was more playful, though not as stable or stiff.
I own a pair of the first yellow MB 108s, after I loved the white ones from the next year, which I was told was the same except for graphics. They were almost unskiable at first. I've been tinkering with them all year (mount position, tuning, base flattening/fine shaping, etc.) and finally got them almost as good as the white ones, but not quite as damp. When right, for me they are a top ski.
From your description of mount points with the Obsetheds and Pettitors, I just have to think you are bigger and taller than I am, but not sure. Or something.
I learned from the horse's mouth, so to speak, where to mount them: Seth Morrison skis at Loveland, and told my buddy going up on the lift that he only skied the longest ones, not the shorter ones (at 160 - 165 lbs.or so, and fairly short - maybe 5 foot seven to eight inches?), and only forward - 4.5 inches forward of recommended line! We tried that, my buddy and I, and many others in the ski shop system my buddy works in, and it worked. Same with the Pettitors, same numbers, same mounts. For example, none of us could ski the 179s, fore-aft problems; all of us liked at least +2 forward on the longer one, the biggest skiers maybe +1.5, but no one I knew. Many of these guys are expert skiers, young and strong, but also expert and older. Some of them are reps or ambassadors for various brands, including K2 guys. Most were at +2.5 to +4.5. (I've detailed in other posts these positions and how they ski - in our experience, for at least a half dozen to a dozen guys, almost all in the biz. All different size guys.) But only the longest Obsethed and Pettitors. (I've used Schizos on all these, so have experienced mounts between -1 to +5. I stick on the Pettitors to +3 to +4.5, but +4.0 mostly. +3.5 next, then +4.5, what Seth used. But +2 to +4.5 are all common with the others.)
So I'm surprised you are talking about minus large amounts. The Pettitors, in particular, are really burly and directional at +2, seemingly for almost everybody, of whatever size, I recall, let alone farther back. For instance, for me, the Pettitors at +2 to -1 are an SG or even downhill ski - charging straight on them on fairly steep slopes feels like moderate speed on most more normal skis.
