I'm getting some empirical contradictions to what I'm sure is good advice. I'm trying to avoid a wall of text with excessive detail, so I'll try to be concise.
I have fairway drivers, a 175 dx leopard and 165 champ leopard, and they go around 260'. I don't use them much because I can throw mids 240' with more accuracy; my drivers (dx eagle x and dx archangel) go 280', left and right finishing, respectively; and if I get the hyzer right, my champ aviar is good for over 200'. My home course is a par 3, so I'm ideally just driving and putting. Bad drives require mids/long putts, but all leopard drives leave me too short to consider a birdie putt.
Here is why I'm currently hung up on weight. I tried to replace a worn dx archangel with a champ sidewinder 165g (entry plastic wear has been a nuisance), and at the same time, I recovered a lost champ valk 150g. If I throw the valk with some hyzer it flies well, but has a tendency to go way high (another issue I need to be concerned about) and/or not too far. The sidewinder even when thrown flat will fade sooner than desired (low s-curves work best to stay below the trees).
I am of the (potentially incorrect) assumption that the fastest disc that can be hyzer-flipped will yield greatest distance, and with the above example, it seemed the way to get over a speed 9 disc was to further decrease weight under 150g, and coincidentally, innova releases just that. I decided to go extreme with the most understable, fastest and lightest disc, and it almost worked. I did throw a personal best (and it finished dead-straight) after maybe 12 throws with the disc.
Its repeated (I'm not disputing this) that throwing putters and mids improves your form, but on a good day, my untrained eye doesn't see big problems with my mids and putters. When my drivers go up 50' high and stall, or finish way left, or turn hard right and roll 100' the wrong way, or fly well and land under 300' problems are apparent (and unidentified).
I regret that I have more opportunity to sit at a keyboard then to throw discs.
