Thinking about my next pair

It's been about five months since I bought my Brooks GTS 9's and I'm thinking about when I'll replace them. I already have five pairs of running shoes although three of them are for trails. My other pair of street shoes are Asics 1130's that are perfectly serviceable but I noticed they pinched a little the last time I ran with them on the bridle trail in Central Park. The past two days I've done my 4:00 AM runs and noticed that I still have an issue with the way they fit at the tongue. It's too bad because they are great shoes but I don't know if I'd buy another pair. A friend of mine just picked up a pair of New Balance 1225's and I started thinking about what I'd look for the next time I consider a replacement of the Brooks. At different times I vacillate between the idea of investing in a pair of high end cushioned stability shoes like the Saucony ProGrid Hurricanes or the Asics GEL-Kayano 15's or a pair of lightweight trainers like the Mizuno Wave Universe 3. I run between 20-25 miles per week with my longest runs ranging between five and seven miles so I don't know how these trainers would hold up in terms of comfort and support.

The mature thing to do would be to swap my low mileage Asics that I keep in my office with the Brooks that are getting close to 400 miles. I could put off my next street shoe purchase for a while if I did that. But what fun would that be!?
