I have a fair amount of experience with both the Explorer {93, 100, and Pro} and the Bonafide {the first three generations}. Explorers are 193cm, and the Pro is a 191cm. Bonafides all 187cm. I'm fortunate to have these either handed to me, or given to me by our son or daughter. They have been affiliated with both companies.
We always "set up" our new skis. Have the bases ground flat, and structured, and have the base and edge bevels set. I say "we" as both our son and daughter have been on the Explorer since it it was in prototype. My son goes through a couple of pairs in a calendar year. I would not say that they are any worse than a number of skis when they come out of the wrapper, but every pair of ours {that I know of} has had some at least issues to correct. Railed bases are common. Some minor cupping on one pair. Our son has somebody who normally selects very good looking skis from the warehouse before they ship.....but they all need to be setup. IME, any ski should be carefully looked at and I can’t imagine not starting out with them “right.”
The Enforcer is a different skiing ski than a Bonafide, particularly the early Bonafide generations, and the first generation of the carbon tipped ski. I loved the way the Bonafide skied when it first came out, and still do. Don't love the newer ones quite as much despite the wider sweet spot. Yes, it has a slightly larger radius, but both the Enforcer 100 and Bonafide can be bent into different turn shapes. I don't think the difference that the OP noticed is attributable to the radius. Might be a good example of why so much more comes into play than waist size and radius when thinking about skis. Like the actual shape, tip and tail profile, the amount of rocker, tail rise, the layup, etc.
The Enforcer 100, in my experience{for me}is more playful, easier to bend into those tighter shapes, more friendly in a bit deeper snow, and though I hate to ski bumps, they are more forgiving there. The Bonafides tend to be a stronger ski in chopped up and cruddy stuff. More of a freight train. Despite the tip flap, I find the Bonafides to have been better at a higher speed. Pretty good ski on wide open groomers for a 98mm ski. Of course they were one of the first in the category, and so many other good skis have come out since. Neither would be my first choice on real firm groomers, BTW.
What generation {what year, topsheets?} are your Bonafides. I don't know many who would describe the Bonafide as being easier to ski, so that sort of surprises me. Of course the Bonafide has really good skiers who have never warmed up to it from it's introduction, at all. I joke with some folks here that I'm a bit of a contrarian. But, the thought that the Enforcers were giving you a hard time, versus the Bonafides makes me think that something is not not right. It's a different ski, different shape with a similar layup, but IMO, should be more friendly.
So having it tuned makes sense. Stan and Dan will be fine for that job.
I wouldn't be concerned or overthinking with respect to the mounting point. People ski them on the line, behind the line...and even some ahead of the line. I honestly don't even know exactly where mine have been mounted. Pretty sure they are mounted on the line. Not with me so I can’t check.
I won't confuse things by comparing 100 to the 93, which is, IMO also a really great ski.
I would start by having them looked at and having the appropriate base and edge set up done. Bet you’ll feel a substantial difference.
Good luck.
