I bought the Respecti and Titan together, both 170+ and in Ultrium plastic. I was confused why my Titan was flipping some in headwinds but the Respecti wasn't. Recently found a flight chart from Prodiscus, and they actually give the Respecti a turn of +1 (rather than the typical negative turn numbers, e.g., -1), meaning this disc is a bit of a monster. I have trust issues when it comes to headwinds, so the Respecti hasn't yet kicked the Firebird out of the bag, but it's definitely getting there. It quickly fights out of anhyzer lines, and I honestly can't recall ever seeing any turn from this thing when thrown flat or forehand. The plastic feels amazing! 

The Respecti is one great disc.  I have it in both Premium and Ultrium plastics, and would say the Ultrium is just a tad more stable, as it fades about 5 more feet to the left thrown RHBH.  the description of the Ultrium plastic, "Ultrium is the ultra-premium Prodiscus blend. This unique plastic has an incredible feel and impressive durability. Ultrium plastic can be compared with Prodigy 400G and has been described as having the taciness of GStar but the flexibility of Innova Star plastic." is dead-on.  Holds good in a direct headwind, when thrown with very slight hyzer, and trhown flat will turn a bit but land softly with minimal fade.  Neutral wind/L to right crossing wind will carry about 340' for me and headwinds knock that down to ~290-300.  Very controllable and extremely consistant.  Both plastics wear slow and have shown no to little "Wear" in the two years I have been throwing them.  Actually, the Ultrium disc still flies like new.  The Ultrium disc weighs 173 g, as the Primium is max-weight at 176g.  I usually don't carry them both, but will swap out depending on the wind.
