Hi Brian. I have never owned a Leica but I do know what you mean about the primes and the Fuji. I found myself yearning for a wider optic on a recent trip abroad and the 10-24 seemed the only way of getting a really wide perspective. I suspect I then told myself that if I sold the 14mm it would nicely take some of the sting out of the expense. I know that I if I actually did that I'd end up regretting it though. Re the zoom. I haven't had much chance to give it a run but starting tomorrow I'm off to try it out. From firing a few quick shots it feels surprisingly good on the XT-1.
