Recently moved to a Monk. Found the rave reviews to be right on the money and am loving this board. The speed, grip, tracking, carving, chop absorption all awesome. The only thing I wanted more of was pop.
So, with a little mod, I found it. Now you too can have the "hooligan" for most conditions and more of a freestyle pop board with the flick of a screwdriver.
Moving the fin in from the tip of the board a little stiffens up the end section just behind the thicker part of the board. I prefer a less tall fin for better switching/sliding and the 45mm Underground fins I use here probably have the same surface area as the Shinns as they are less tall but have a longer base.
Underground fins and their screws fit perfectly so all you have to do is drill one new hole per fin. It's a little tricky getting perfect centers and you must make a jig and make sure the jig fits the fins first or you will end up with either badly aligned fins or worse, useless holes in your board. Of course there's no reason you can't just use the Shinn fins.
So anyway. Now I have two boards in one. Standard mode: all the stuff you love about a Monk. And freestyle mode for more pop. In more pop mode you do lose a tad chop absorption but it's minimal and given the fins are further forward some carving surefootedness. But not that much.
Since you are only drilling through the end thin section and not through any wood core or anything I doubt there is any issue with new drill holes there. The new hole looks exactly the same inside as the existing holes i.e. the existing holes do not appear cored with any material inside or anything.
Anyone interested, post here and I'll tell you how I went about it.
Interesting edhead. I like your work
At Kite Surf SUP we import & sell the Shinn boards so very keen to learn more.
I find ALL the Shinn snowboard styled boards have awesome pop - its one of their big points of difference (imo) - so Im surprised by the need which made you experiment.
Can u tell us just how much difference this move makes in, say, percentage terms or maybe just describe the difference for us.
Tempted to try it but putting another hole in the board ??? Big commitment needed there.

Hard to say in % terms. Just noticeably more spring in its step. I don't understand the reference you make to Shinn snowboard style boards. Maybe the Shinn board pop is something one can dial in better over time; I've heard it said. But coming off my other more freestyle oriented board, which I really didn't like for anything except its pop, I felt I wanted just a bit more spring in its step.
I just saw that if I stood on my Monk on the ground or put my hand in the foot pad and flexed the tail, there was a lot of flex just behind the thickest part of the board (which is what makes it ride so comfortably I guess). But I figured if I moved the fin up a little it would stiffen that section up a little and thus add a little spring. It also seemed that after putting my underground 45mm fins with the longer fin base (which by the way didn't subtract anything from the board except make switching/sliding easier) that the trailing edge of the fin was unusually close to the end of the board so there seemed a little room to move.
Anyway, I'm a happy camper with my experiment. But you're right. Drilling holes in the board was big commitment. Remember the old expression, 'Measure twice, cut once'.
Those that feel the same way and like the idea but are too scared to take to their Monk with a drill could always instead get 'The Street' as it seems they have combined the Monk ride and the Supershinn pop in that board now.
Edhead you could be onto summit here patent it, a board with multiple feel settings you could design a track in which the fin slides, the only down side I can see is when tts are made they usually have solid epoxy in designated places and you just may of drilled outside of that also a little dab of silicone in the new hole before you put the bolt in will stop any possible ingress ,good idea though, I wouldn't dream of putting a drill to my monk it'd be animal cruelty
