I just ordered a new 31.8 carbon handlebar which is an upgrade from my 25.4 Truvative L.E. and now I need a new stem. Reviews here on MTBR show that the Kore Elite and the Thompson Elite and X4 are considered top of the line but is either better than the other? The Kore can be had for $50.00 including shipping and the Thompson is nearly twice that much. Is the Thompson worth the extra money? I ride mostly intermediate XC trails with small drop offs. I weigh close to 240 with all my gear. Thanks in advance for the advice!
