We're all for exploring neat details because this is the number one disc nerding site around outside the industry and we have some members working in DG. Generally speaking all disc classes have flipping, straight and non flipping hard fading discs. The Teebird is a good reliable tight place sidearm disc. People have thrown well over 600' on flat land with sidearms but that club is small. Backhand the Teebird held the world distance record for 45 minutes with a 247 meter throw, that's over 800' so it is more the thrower than the disc for your distance potential.
Mids that are straight are way easier to place accurately on the fairway because they can be point and shoot devices. Those discs usually won't tolerate unclean form FH even though they have some user error protection backhand. A great difference between mids and drivers is nose angle sensitivity. A mid thrown nose up won't fade out so early if thrown nose up so it is more forgiving to that error. The tricky thing is that sidearm is not as susceptible to that form flaw as backhand at least out to 300' power with drivers. If a mid pops up and stalls chances are that it won't be moving fast enough to move a lot sideways. A driver can. The wicked thing is that a straight mid thrown fast and high without stalling will move more sideways than a high non stalling driver in most cases.
Straight mids flip over easier and wobble for longer than drivers so they penalize more with off axis torque. Something that could be hampering your progress. So they are great diagnostic tools for cleaning up your form by showing that you did something wrong. Hopefully armed with enough information also just what you did wrong so that you can try to correct that with the next throw.
The really difficult test is to drive with even more nose angle insensitive and OAT sensitive straight putters. There are plenty overstable putters and mids that mask a lot of user error while being fairly nose angle insensitive. No driver is truly tolerant to nose up throwing but often times putters of all sorts and about half to two thirds of mids won't penalize you too hard on the course if you throw nose up.
Depending on the disc the stabilizing force of the spin may be weaker than with a heavy version. A lighter disc should be able to be thrown faster out of your hand than a heavier. At higher speeds you can make the disc exceed the cruise speed where it is supposed to be flat. The more you exceed the straight flight speed of the disc the more the disc will turn.
There may be a personal grip/form issue at play with lower weights too. You can hold the disc longer for the same grip power with the lighter disc. If the disc pivots more and the front drops lower than with an earlier slipping out disc the nose angle is oriented front of the disc down. That angle of attack vs moment of inertia will turn the disc dramatically more. Throwing nose up is nigh impossible to turn the disc but throwing the front of the disc well lower than the rear is very helpful to getting the disc to turn over. Center of lift changes.
For a more physics i'll refer to our resident PhD in physics. John?
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
