i have a 2017 Slice which seem pretty similar to the super slice and I love it. The bike is light at 17lbs and handles like a road bike which makes it enjoyable to ride. I did one IM on it and it was fine with top tube bento and bottle between bars and rear. It may give up a few seconds but comfort counts for something. I put some omega brakes on it and found it easy to work on and travel with, this bike made so much sense for your average triathlete but may people were swayed by more fancy looking bikes that cost 2x price and 2 lbs heavier.
