The Tui is an understable putter that will hold lines on more controlled shots. I find this disc most useful for low power upshots 100-150ish ft. It will hold the line you put it on and will just glide and glide and glide. Throwing with more power, for me, it tends to hold turn and not come out. 

Overall, I think this disc would be situational for anyone who has been playing for a while. For newer players I am not sure... as mentioned I think it requires some control that new players may not have developed yet which could cause some frustration. I think this could be a wonderful disc for players who want to go play a putter round and work on controlling power and angles to get a variety of flights out of it.

I've tried other understable throwing putters like the Fierce, and none have thrown as well as the Tui. Great hand feel, love the shallow rim. Thrown flat with power it will hold turn the length of the flight. On slight hyzer, will either flip to flat and ride straight, right, or even hold the hyzer depending on power and launch angle. One thing I didn't expect was how it throws forehand. For forehand approaches you want to add some turn to, the Tui will achieve that without needing to add too much juice. Such a versatile disc in great plastics.

Amazing approach disc. It'll hold any line you put it on and can glide for days. Highly recommend this for anyone looking for that slow approach disc that'll go go dead straight on a rope. Put a touch of hyzer on it and power back a little and you'll get a nice stand up/ pushing hyzer. It'll hold massive anny lines, and is also very easy to hyzer flip to turnover. The cosmic plastic is very durable also. Lots of lava rock where I live and play, still looks fresh and fly's like it too

This is an amazing straight flying putter for beginners. As someone with intermediate power, if released flat with a RHBH throw, it will turn to the right and stay moving to the right. If released on some hyzer, this disc will flip to flat and ride straight with almost no fade. The tui can be touchy, but after some practice, this will probably be your furthest flying putter! 

RPM designs some of the coolest discs I have seen and this disc is no exception. I personally would not consider this an all purpose putter but I love this disc when I need to make an anhyzer approach shot. This disc does not fade at all and will hold an anhyzer line all the way through. Did not give five stars because it only fills a niche role for me but fills that role very nicely and deserves a spot in your bag.

Might be my favorite disc of all time.  No wind/tailwind this thing is great.  Excels at anhyzer puts and awkward lines. Plastic is top notch as well, durable and grippy.
