Boring Disclaimer Stuff: 26yo, 6'1", 165lbs, RHBH, Intermediate (I'm being super generous here; 2 years playing, one year regularly about every weekend).
What I Got : 175g Champion, 168g Champion, 175 Champion Glow
I love this thing. This was the first high-speed driver that really 'clicked' for me in the higher-end plastics. I had reached some distance with cheaper DX, pro, Blizzard discs (Orc, Wraith, Beast, Katana), however those get beat in fast and become unreliable about two rounds past their 'sweet spot'. I don't have the arm for a Destroyer, but I'm a sucker capitalist and I'll be damned if you can stop me from buying one and trying, Paul Mcbeth. Alas, if you're a mere mortal like me, you'll need some under-stability to go the distance (no shame in that BTW). The Tern got me there.
The Champion plastic these are made out of is stupid durable. I've hit rocks, trees, bears, fences, people, dead-on perpendicular and not even a scratch to speak of. On top of their durability, I think Champ plastic looks great. I have two blues I bought at different times, different stores, and they both have a bit of swirlyness to the color. My Champion Glow is slightly more stable than Champion, however I think the flight paths are comparable. The main difference being the glow is more rigid with a little less grip.
As for the shape and dimensions; I simply like the feel of the disc in my hand, which probably equates to some confidence when throwing it (did I mention I really like this thing?). I'm 6'1 with some mitts, but I usually don't like wide-rim drivers. The height of the Tern (bottom of the flight plate, to the edge of the rim) is pretty shallow compared to most discs I've tried, which for me is a plus; may be something to consider if you prefer a bit more to hang on to. In Champ plastic, this thing is a pancake. I'm told that generally means less glide and a bit more nose sensitive. I don't have the slightest idea how one would measure 'glide' but I'd say 6 is accurate, if not optimistic. As for nose sensitivity, that I can say is accurate. Keep this thing level. I have yet to throw a Star Tern, but from what I've noticed just picking one up at the shop, the profile is extremely consistent between pro, champ, and star. GStar has a bit more pronounced dome to it.
I don't have a cannon of an arm by any means, but as I'm progressing and adding more power to my RHBH throw, the Tern has accommodated and provided more distance. You will need a bit of arm speed and consistency to access the initial high-speed turn so if you are hyzering out early left every time with this disc, look for a lighter weight, or hit the field for a couple weeks. Even 10 grams can make a huge difference! This is a very versatile driver for me for where I'm at right now. It's been a great learning tool as I can occasionally put too much on it when powering down and it will carry right, telling me to back off, or change my angle of release. The one mark I have against the Tern, honestly is it's inconsistency in a headwind. I don't have a figure or certain mph to look out for; but if you are getting gusts directly at you on the tee box, stable up (I like a C Wraith). I can throw my 175g on a severe hyzer but it's still a toss up (punn intended) weather it's going to flip up and over all the way or not. I avoid throwing my Tern alltogether if the headwind is anything substantial. That being said, if I had to take just one driver to a course, I'd take a 175 C Tern due to its versatility.
If you're regularly flipping your Katana or DX drivers and want to get some more consistency with your RHBH drives, check out a 165-171g Tern.
If you're regularly flipping your max weight Destroyers, Stilettos, & PD2s and just came here for the giggles, go throw a manhole cover and leave us be.
