Long or short?

I've ended up with two frames from a certain English manufacturer, love the bikes but this is more of a geometry question. Frames are identical in stand over and chainstay length but one has a longer toptube and wheelbase,
I'm going to build one light for everyday riding trail etc and one heavier for Scotland/Wales trips.
Question is should I build the longer or shorter frame as the all mountain build?

    You should have the same size for both. Whats the difference in length?

    One is a prototype frame and isn't really given a size, it is a mixture of a small frame seatube and stand over height etc with a medium length toptube to give more space to move around on the bike. Toptube is 25mm longer from one to the other.
    My thinking was the longer bike would run a shorter stem to retain cockpit size but have a more stable longer wheelbase for trips away...

    Yep longer bike for the gnarlier stuff and shorter stem. Shockingly the protos and subsequent production run was a flaming good idea IMO. Despite my dislike for the brand, this and their options on colours are something I wish more people did.

    I'm guessing it's an Orange 5...

    Generally, a longer top tube will give you more stability and better climbing ability; they are usually for XC racing.

    "Long" is for tall people. "Short" is for short people. Which are you?

    Probably depends on component choice (fork length, wheels etc) as much as the frame’s length.
