Right on in your assessment! Wear and tear is a part of the trimming, but lawsuits are a huge factor. Not that the park will ever be honest about it. Why do you think most coasters today have such wide transitions and a large curve radius plus track angles on most turns? MF is a great coaster due to its speed, but did you ever take a look at how wide all the transitions are (this is just an example not a MF bash---I love this ride)? There is a reason for this type of design. This limits g forces and thus potential injury forces to the body. Some would argue that this also limits the fun factor! I will argue this if you would like me to! :-) BM (my favorite steel company) is known for smooth transitions that limit g forces for any prolonged time period. They still have great rides, but they do not offer the strong g-forces that could make a great ride classic by turning up the intensity. There is a fine line between intensity and fun factor which differs from individual to individual. Wooden coasters normally get their fun factor from the g-forces created by speed coupled with track angles and length of the turn radius. Once the ride is built, it is cost-prohibitive to change the radius of the turns and track angles. Occasionally their are major track reprofilings (Rattler comes to mind), but trims are usually the solution of choice. There are countless examples of great coasters that were tamed through the trim (Beast, Mean Streak (maybe it never was a great coaster---but it was a lot better than the pathetic present state), most California woodies except Ghostrider and the Dippers, etc.)! You should always try to ride any coaster, but especially wooden coasters in their first year of existence before maintenance crews and lawyers ruin the ride experience. Most park legal issues never reach the public's attention. Settlements are the norm. This is the society we have created. Remember that the next time you vote (if you are old enough to vote)! Judges and lawyers are out of control in many areas of society. You don't think about it too much, until they start messing with the things you love. This has been going on with rollercoasters for quite some time now. It is only going to get worse though! The slippery slope started a long time ago! JMHO!
