Hi, I am looking at getting a 29er and while talking to a number of different people they have suggested that I should look at going a frame size smaller than I would normally to counter act the extra length and reduced "chuckabillity". I am about 175cm, so would normally be looking at a medium. Should I go for a small? What is the general opinion out there as I don't want to end up spending all my money on a bike that is either too small for me or one that feels numb in the technical sections? My choices will be limited to hardtails and I want to be able to do marathon events and not just play around at weekeneds.
