I have a diesel geek sigma 5 for my Golf 1.8 TSI and I love it. It makes shifts nice and satisfying, and it's not too short. I've personally had no issues with it in the cold either. The only little thing is related to installation, which is the side-to-side adjustment is quite sensitive. Even when you adjust it using the lockout pins on both the shifter and transmission side, you may have to finely adjust it to get the shifter to slide into gears completely perfectly.
