The F5 is one of my work horse FW discs and can’t imagine playing without it. It slots in right between my understable Maul and my Stable/Straight Opto Glimmer River.
I have a 400 max weight and a 750 max weight. The 400 is just ever so slightly domey, but just ever so. It’s almost flat. Then the 750 is flat. The 400 plastic has the look of Champ or C line, but it’s more along the lines of Star or S line in it's flex. The 750 plastic is much stiffer and more like a Champ or C line in terms of flex/stiffness. And it’s about 50/50 with its opaqueness. You can’t see thru it, but it definitely lets in more light than an opaque disc, giving it a gorgeous look out in the sun! The rim shape on both feels amazing in my hand and is one of my favorite discs to hold. It also feels amazing for FH’s, since it’s not domey and has a flat to somewhat bulging rim shape (like an FD2), instead of concave.
The flight of the 400 is more indicative of a “normal” F5. It’s a 7/5/-2/1 ish disc. More like a 7/5/-1.5/1. When thrown at controlled speeds and slight hyzer (what I’d call a normal shot), it flies with -1.5/1 turn and fade. It leaks 5-10’ out right, stays there, then has a baby fade at the end. But with a net flight of ending a little right of center. If thrown harder, it will turn more. If thrown flat, it will turn more. If thrown on a 45* hyzer angle and hard, it’s a money tight woods hyzer flip disc. But, it’s a bit touchy sometimes and has some random flight paths occasionally. Sometimes I’ll throw it on a fairly steep hyzer and smooth and it will take off right and just keep riding that turn and never come back, when it should have gone dead straight. Other times I’ll throw it pretty flat, thinking it's going to turn right pretty hard and it barely turns at all. It’s kind of weird. But most of the time it goes where I expected it to go.
The 750 is a bit more predictable overall. But It has a bit of an odd S flight though, even though it’s super stiff and should be more stable. It turns right quicker than the 400, but always comes back left with about 1.5-2 fade. It’s so strange. ALWAYS. I can throw it flat, hyzer, steep hyzer, and it always has a form of an S flight. But I can count on it being more predictable more often than the 400. And they both don’t do well in the wind. Especially the 400. It can get squirrelly in any sort of wind above a slight 5mph breeze. I’d say the 750s flight is like a 7/5/-2/2. So strange.
Also, neither one is what I would call a LONG FW disc. They are more like control FWs, with most of my other FW’s all going longer distances with the same amount of effort. But it’s not massively shorter. Maybe like 10-20’. And both are great on FH shots because of the thinner profile and rim shape. Great for hyzer angle release FH shots and good for recovery shots out of the woods or left side of the FW when you need an understable disc to throw out to the right on a FH and let it keep curling back left.
Overall a really good FW disc that I use often. Just wish the 400 was more predictable. I love how predictable the 750 is, but don’t like the flight path. LOVE the flight path of the 400, but it’s kind of unpredictable occasionally. Not often, but it happens so randomly and I can never understand why? Usually when you throw a shot and it doesn’t do what you want, you know exactly why. I put too much hyzer on it, or I threw it too hard, or I didn’t start it out left enough. But this 400 just randomly flies places I’d never expect sometimes, and that’s frustrating. Although, it’s never too bad and never ends too far from where I expected it to go.
Overall I’d highly recommend this disc, but with the suggestion that you try a bunch to find one that you like the flight of best. And is predictable. I can see why Kevin Jones likes these so much now after using these 2 for a few years and getting to know them well.
