I'm getting ready to order a TT 6 point harness and I'm looking for opinions. I will be tracking my gen 3 about 3-4 times per year. The options are the basic 5003 style with snap in hardware or go with the 'made for Viper' 6004 ASR that seems to have a lot of bells and whistles that I may not need. My question is is the ASR harness that much better for a track days? Are there any options that are must have? The ASR has double adjustable shoulder straps. Is this really needed for comfort? I won't be using the harness for regular street driving.

Thanks
