Having that shorter track has been very, very helpful in certain situations. I'd consider getting an even shorter one, although I may just cut one from the "original, original" narrower Festool rail I have for that kind of thing since it just sits around and isn't really worth anything for resale. (it will not mate with current generation tracks). The HK series of Festool saws with the short track that sticks to the saw are a really nice solution for carpentry in that respect. I'm not about to spring for one of those, but the value of a short-short track is still there for me sometimes.
