The footnote for 7.37 says there are "several criticisms ... against the IIFT..." Besides making it easier to strip concealment, and providing more PTC results in general, what other concerns are there? Just curious as I'm considering switching.
Check the three pics (scans of the basic debate):
This debate has been gone through over and over in this forum ad nauseam and it comes up every now and then. With regard to the arguments, nothing has changed since the early 90's which you can read above, so if you want to save some precious time of your life, you might as well skip over all those debates you find here in this forum.
As you see above, the strongest criticism was all the extra Concealment-stripping opportunities introduced by the extra Pin results. This has been mainly addressed by the CTC (Conditional Task Check), which you only have to take if you are unconcealed. In case you are Concealed, just nothing happens on a CTC.
One thing to remember is:
If you play at tournaments, the director usually specifies the "default" (in most cases the IFT). If the default is specified as IFT and the two opponents have differing preferences, then IFT it will be. I know of no tournament that makes the use of the "IFT" mandatory and explicitely "forbids" the use of the IIFT. This would be rubbish in any case - and even if so, what would keep to players that want to do so to play the IIFT anyway?
Besides that my general impression is that the whole debate is a tempest in a tea pot. Some argue that IFT/IIFT makes all the difference in the world. Some argue the same for normal dice/precision dice. Others say that the difference is marginal compared to other factors, for example, WHEN you roll those Boxcars, the general balance of the scenario, the relative skill-level of both players, etc.
I believe that for many the IFT is simply more convenient since they have memorized it - and it's less columns to memorize than the IIFT. Others like the IIFT better simply because they can "use" every FP and don't need to drop any.
Bottom line:
I am usually sceptical of any kind of doctrinal orthodoxy into any direction. If you want to keep the fun up, your chances are increased if you keep that in mind.
Live and let live. IMHO it's 90% about personal preference and 10% about "real" differences, the latter of which are not overly relevant compared to other factors.
