Absolutely love Sparks! Specifically in the Recycled plastic. This disc is a better Teebird in everyway. Its super stable and yet beats in perfectly for every shot you can desire. Im carrying 4 sparks in the bag currently from crazy overstable to a little understable. Use them for shots 315-400ft shots and they are so predictable. Advise anyone to pick up a spark but try to get a recycled and it will replace almost all your 7-8 speed fairway drivers. 

I am basing my flight numbers off the recycled plastic.   which is by far my most used and favourite fairway driver. 

i have used sparks in all plastics and could easily use one mold to cover all fairway roles.  a light weight recycled one for those straight and slight fade shots. (dare i say 11x teebird!?), a gold as a back up. a mid weight opto for most driving duties in windy conditions.  and max weight opto for flicks, rollers, and saving me from trouble.   (all my opto's are flat).  i use the sparks like a justice power it down to get the same flight and fade.  the moonshine is a xxx type disc where it will fade no matter what!  it is my utility disc.

if you are trying to cut down on molds in your bag, this one mold could help to simplify your game.  

I love the Spark and now my Spark collection is complete after realizing what a great straight fairway driver this disc is.  Give is 60-70% power and its stable with a nice stable fade.  Give it 75-80% power and it's straight and far all day long.  Bump it up to 85%+ and it will turn for you...or give it some anhyzer and watch it ride the line and finish flat.  The whole line up of Sparks in different plastic gives you very different discs...from freakishly overstable in the Moonshine, to pretty straight and easy in the recycled.  All the plastics feel great and the rim is very comfortable.  Releases very clean, I feel very confident throwing this disc down a tight hallway or having to hit a small gap.  It's one of those discs I know I can rely on. 

The recycled spark is an amazing disc.  I would compare it to a fresh teebird, rival or eagle.  Not much turn, plenty of glide and a very healthy fade at the end.  Workable.  Loving this for hyzer shots out to 350 feet.  The opto spark is a completely different animal.  Over stable!  It's replaced my 11x firebird.  Awesome for thumbers, flicks and flick rollers.  Love having a single mold that can do so many different things.  Dave Feldberg and Lat64 knocked this one out of the park.  

For those that are looking for a Trilogy alternative to the always recommended Teebird, look no further!  In the recycled plastic this one feels and performs just like a G-Star Teebird! I would 100% recommend this to beginners!

Recycled/Opto 170. Still up in the air on it. According to Feldberg, he wanted a straighter XXX, a striker line with a XXX finish. So straight with a hard finish. The opto is the first version of this disc and it is very overstable. Nothing really to it besides os hard. Now the recycled is what he wanted. A fairway driver that will flip and ride with a hard finish. I can get my recycled to have a flex that almost is a turn and ride that line with a hard finish. I recommend to get the recycled and not the opto.
