It kinda depends on what your slant on riding is really, if your preference is DH, and more aggressive stuff like Andy m for example then your ideal build would heavier duty.
I just sold a 5 inch travel XC bike (stumpy) and with very small changes to it, it was comfy at anything from an XC race to a day doing the Plenny run until my hands fell off. So recon that was the ideal bike for me at the time, now I have less time to get away to bigger hills I have built up my Scandal, which with the build I have will do all the riding I want, local loop, commuting, the odd XC race, or still be pretty happy at a trail centre.
I call it a colonial build, as appart from the drivetrain thats all Shimano, every other part on it is either UK designed, or US designed and made. On One. Hope,USE, Thompson, Maverick. (and a random Scott saddle until charge spoons are back in stock)
