I have the opposite problem, I throw the force on average 400 feet but my Crush goes further around 430 comfortably. My nuke flips if I try throwing it on an open hole or in any wind. I have to use it uphill to get it to get any decent distance.
pro boss or beat in star destroyer are the 2 discs i have thrown the farthest. champ boss is more consistent for me though, so i reach for it more times than not. still experimenting with my katana. all of these discs bomb for different throwing styles.
I've thrown all these discs save the Force. R-pro Boss and pro Katana are the farthest I've discs I have. I feel that I have more consistency with the Katana than I do with the R-pro boss.
If you wanted to know what these discs do for real, we should be talking to the pros. Blake T @ discgolfreview.com makes the Joes Flight Chart and has people throw discs for him (this is what I've heard). I think he'd be a good person to ask.
I've only tried the first 3 but consistently i would say WRAITH i cant get a bomb out of the BOSS but that was once on an open field and i could only get that drive once out of about 12 shots but im sure if i spent more time with it i might be able to get it down. I dont like the Destroyer even though i know there are a ton of Destroyer fans out there. My buddy is one of these fan and ive seen him bomb some huge shots with the destroyer and it was a really light disc so with a 170-175 Boss im sure he could send that thing cruising cause hes got one of the farthest drive is seen first hand.
I think your problem is. You throw to far! lol!! My average is in the 300 to 320 range. But with my Nuke or Katana. I can get anywere from 10 to 20 feet more. So if you want to throw the Nuke with more consistancy. Stop thowing so far! ;)
