As an alumnus of UND, all I have to say is, although UND may have some seemingly stupid rules, in the end I learned to appreciate the level of discipline it fostered.
For example, you may think checklist organization in a Piper Warrior may seem silly (and if you compare this to "traditional" general aviation flying - it is silly). I believe this helps you to develop discipline in standardization. In the professional world of aviation you have profiles, checklists, call outs that require you to have situational awareness of what tasks are to be completed in very specific phases of flight or maneuvers. You will hopefully carry this with you to your first professional job.
As for the weather restrictions, I too sometimes wonder what the SOF is thinking, but if that's what they want to lay down, then so be it. Better safe than sorry, IMO. I do know that of 800+ students, there are likely a handful of idiots that will get themselves in trouble if they are given the opportunity.
I recall hearing a transmission that went something like this on an extremely cold winter day last year. Temps were below freezing at the surface and aloft with an overcast layer above 3000' AGL or so.
"Grand Forks Approach, Sioux ## requesting a block of airspace so we can get some actual in the soup!..." (sounds excited, eager)
I have a huge '?' in my head knowing they just requested a block of airspace above my altitute when temps aloft were below freezing.
Approach gives him his block of airspace.
A minute later...
"Approach, Sioux ##, we need lower! We're picking up some ice!..." (sounds excited, except this time scared).
Go figure!... Doh!
I do recognize the political intricacies of dealing with Flight Operations, but I don't see that as a reason to avoid UND all together unless it bothers you THAT much. I did start my flight training Part 61 (did my private SEL) at my local FBO and then transferred into the UND program. What I found lacking with my Part 61 training was the thoroughness and consistency of my training. The airplanes were old, equipment outdated, and just overall shady in general (improper MELs, balding tires, interiors shot to hell). My instructor didn't really have a solid plan for me. He'd often ask me "what do you feel like practicing today?" (don't get me wrong, sometimes flexibility is good). But in the end it dragged on because it was expensive and there were no real time constraints.
Your training at UND is what you make of it.
