I have flite 230s and the Minimus trail. Two important considerations: they have different fits and different uses. I use the Minimus for essentially all training, including runs over 4 hours. As frequently noted about the Minimus, I like that my feet can comfortably splay out. But this is one reason I do not like it for races; at a faster race pace that comfortable splay becomes room to slide in the shoe. Furthermore, in a race I want a full covering sole. In training it is not a problem to feel small stones poking through the exposed midsole between the vibram knobs, but again in a race this is not so desirable. The flite 230 fit snugger on my feet and provide better underfoot protection. But as stated in one reply above, the uppers do not last on these very well - giving out behind the protective rand as mentioned. Also work well as a road shoe, when the need has arisen. I don't get much more than 500 km out of a pair of flite 230s, whereas I have at least 1000 km on each of two pair of Minimus, and they are not done yet.
The Minimus are also not good in muddier, wetter conditions - again more critical in a racing context. The sole does not grip on wet or frosty rocks, nor are there any lugs to grip in mud. Races in such conditions I have used roclite 285s, but may consider in the future Walsh elite racers (but I need to try the fit first). For races in drier conditions I would like to get my hands on the new MT110s from New Balance, which now has the same last as the Minimus and same 4 mm heel-toe drop, but better underfoot protection.
So, keep in mind the question of fit and think about what your specific needs are for the shoe you are looking for.
