Plow Advice for D17

Since I installed the used factory 3ph on my D17 IV, I have been looking for a good set of 3 ph, 3 bottom 14 or 16 inch plows. So far, I found a set of AC semi-mounted (don't know the model number), and also have found a nice JD and Case fully mounted, but I'm still looking.  I will have the traction booster hooked up and functional on the D17. 

Ignoring the color for the moment, any general advice on advantages of semi- vs. fully mounted vs trailer, and are there particularly good models I should be looking for?  While I like the AC, the idea of being able to buy replacement shares and such seems to favor finding a plow with active dealers.  I had always heard that some of the older JD trailer plows were among the best ever designed.  I will need it to turn under trash when needed without plugging. 

Any general advice would be appreciated. 

A semi mount plow in my opinion is a nicer plow to handle and set, its not as easy in tight quarters but out in a field I would prefer the semi mount. All colors aside any of the older plows AC, JD, IH Case Oliver etc all did a good job, but if you want the king of plows find yourself a White.

Thanks for the correction, missed the word factory. 

Plowing of trash is a pain, wish I had a good answer to that one.  I had to stop four times today just to dig out blackberries roots and stems, only a small patch about 20' long.  Getting ready to try and plow about two acres of spotty patches of blackberries, going to disk them first and then plow, see if this helps.  I'll be posting pics of the plowing and what I have learned about SC plows and what has worked for me, and or ask about any other ideas, we have about 20 acres of that type of ground to reclaim over the next few years. From small trees to all types of berries and weeds. I would no-till corn, but don't have a planter and no-one close enough willing to plant it.
