I think optimal AoA for glide in trackingsuit will be much higher than 5 degree. Trackingsuit is nowhere near to the optimal airfoil. I have a outside wideo of me tracking from Brento in classic PhoenixFly trackingsuit with GR around 1.4: https://youtu.be/P_slFCiOHkc It's not the best part to judge the optimal pitch angle, because it is during a small flare. So to keep the speed and GR constant the position will be more head low for sure, but definitely not 35 degrees down from horizontal.
I have been flying barracuda FS for more than a year know. Only one thing which I don't like is standard pocket. It is in armwing and it is hard to get to it when you are in wingsuit. But that is easy to fix, just buy one with extra pocket ar tail pocket option. Build quality is excellent. It is the stiffest wingsuit from what I have been flying (which is TS Jedei and S-bird, PF Havoc, S-fly Verso and Hawk, Redline Swurve).
