I read here that Tiffanie plays these... Any chance you could post a comparison of the 2? Ive read the f100 tw review, curious how the q5 compares and the differences in comfort between the 2. I have the q5 demo now, it feels good but the demo also has full multi, which i would not be using in the real world. (would go poly/multi). Is their a substantial difference in comfort in the 'kinetic' system vs donnay xenecore. Ive had some elbow in the past, play daily and am wanting to stick with one of these long term. (using a volkl powerbridge 7 currently) Thanks!
