I'm in the process of saving up for a new frame. I really love the rectangular down tubes that are on a lot of aluminum track frames. I've narrowed down my options to a 2011 Leader 725TR or Affinity Kissena. I haven't been able to find any straight forward reviews for either frame, but I have heard some things towards Leader as a company. Such as, they are more about quantity than quality, and as such, their welds aren't as high of quality as other manufacturers. But, I've also heard they give a lifetime warranty? I suppose that evens out- break a frame, get a new one for free. But, does anyone have any experience riding on either frame? I'm just trying to get a new commuting bike, there isn't a track near me to ride exclusively. $750(not including the other parts) is a hefty price for me right now, so the $400 Leader 725 sounds like a better choice for money.

Thanks
