So I got the River Opto and 150g S line FD in finally. Went out this weekend to chuck them around and have a quick practice sesh and the FD definitely is interesting!
It feels SO weird at 150g, haha. Like a toy. And since the top plate is SO thin, it's not very stable feeling in my hand. But... the few throws I had with it were promising and interesting. They all went either dead straight or just kind of went right and stayed there. Maybe like 5-10' right of where I thought it would go, then just stayed there with a baby fade at the end. And a hyzer flip line would go out straight, flip to flat, then fade out left a little at the end. So that was good, but overall, the super light weight feels weird and so does the floppy thin top plate. So we'll see long term how that works out. Not sure it will, but it's something to work with for now.
And so far, I don't know about the River. I threw it like 3-4 times and none of the throws with it were great, so the flight wasn't indicative of what it actually can do probably. It seemed more or less like my normal 175g S-Line FD's. Good feeling rim, fairly domey (which I don't ever like) but not too much and comes out well. I was working on some things so most of my throws were not good, and it always seemed like the River was one of the shots that was really bad (because I was working on some form issues, not the discs problem). But one of the throws was promising! I threw it way too low, but it was zipping along dead straight for the whole flight with a baby fade at the end. I think it will be almost like my FD's, just a tiny bit more glidey and tiny bit straighter overall.
So both are good options in my bag for now, to fill that shot I'm looking for. I'm also getting more used to my Prodigy F5 in 750 Spectrum plastic. I hardly ever throw it, because usually it has this odd S shaped flight. Which it shouldn't! It should actually just leak out to the right the entire flight, and then have a baby fade at the end with the numbers it has 7/5/-2/1. But instead it has a very pronounced fade at the end and when thrown well, has a fairly large S shape flight path? Like it thinks it's a Innova Tern or something, haha. But lately, I've been trying to throw it more to get used to it, and it's coming alive now! My form is still not great and having a SUPER hard time figuring out how to throw properly after two years of this silly sport with tons of practice. But... I am getting more distance with less effort the last few months and when I really get a heavier feeling throw on the F5, it really zings out there and the flight path is more in line with what I want. When I throw it really well, it's like a 7/5.5/-1/.5 The EXACT disc I'm looking for! Tiny push out right, but straight, then just sort of fades a few ft at the VERY VERY end and overall, ends up dead straight! So I think working on my form and just getting better will make that disc my favorite for this shot, and in the mean time, I'll have the River and 150g FD to use!
Thanks for everyone's suggestions and help!
