This is my favorite disc from Prodiscus, and Ultrium plastic I now prefer over K1 Kastaplast as my all time favorite plastic.  My results/precision with this fairway driver are unparalleled vs. any other fairway driver, and I find the moderate overstability to be exactly where I want it in the OS fairway driver slot.  The lower fade when compared to a T-bird or Stal is much more predictable for me, and this has plenty of fade to get around obstacles while still getting all of the distance I'd want out of a fairway driver.  The fade is buttery smooth and the range of power I can give it while getting a predictable flight again goes to the Titan!

Mine is a notably light at 166 grams, and this baby is so perfect that I'd be reluctant to try the disc in other weights.

The shape of this disc fits my hand so well that it even feels pretty solid in the hand when I hold it w/o my thumb... no wonder this disc always releases so nice for me!  I have average sized hands.

Flex in a plastic has always been a deal breaker for me, so when I got my first Ultrium disc I'll admit I was a bit disappointed prior to throwing their stuff because I heard a pretty all in endorsement from a pretty big K1 Kastaplast fan, so I was expecting it to be firmer and I was excited to find a company that rivals Kastaplast's feel while opening up a lot of different molds because I love Kastaplast plastics, but their flight paths I don't love in most molds.

Anyway, if K1 is a 3 on the flex scale, and K2 is a 9, Ultrium is probably about a 5 or a 6 in terms of flex.  It melts into the hand and I haven't seen any negative consequence to the level of flex like I have w/ other gummy attempts in the other brands.

The Jokeri is also a winner, but a little slower would be nice.  The Fasti is VERY understable, and I'm not impressed with the feel of the Respecti so I didn't throw it.  The Sparta has a great feel and might be a winner for a push putter, but it was a bit understable for me.  The Razeri was too overstable for my liking, and the Stari was a bit too US for me, and I did feel like the Ultrium was a bit too flexible in just the Stari mold, but that mold would be great for a beginner.  The lazeri seems like a winner, but I haven't thrown it much yet.

Excited to see Prodiscus launch a little more officially in the States in 2018.
