As you said, there are different opinions on this. I just hold the opinion that getting basics down with easier discs is more beneficial in moving to upper levels.
Exactly. While there are many different ways to go about things, very few of them will give the best, fastest results. I don't care if someone chooses to use an inferior method to learn. I want it to be clear that the method is inferior, though. The fastest, easiest way to go about this isn't an opinion, it's a fact. Spending time learning to control a disc that's unpredictable is a waste of time. There is never a situation where you'll need that skill since filling your bag with predictable discs will always lead to better scores than choosing to throw unpredictable discs.
SunIsBlue15, I guanatee you'll eventually find that the Archangel is not a good learning tool, that it is too unpredictable and it will either lead you to reaching a plateau earlier than you want or you'll switch to something more predictable and begin learning many times faster. Whether or not you choose to come to that realization now is up to you.
I get my information from Blake at Disc Golf Review. He got his information from various pepople who have either been playing for decades or who own disc companies as well as his experience teaching dozens of people to play. I have ignored his advice in the past but have come to find that every single thing he presents as being the fastest or best has been true. I'm not speculating or just going off some sort of gut feeeling. What I'm presenting has worked for lots and lots of people, including myself. Before listening to him I had maxed at 350' using high speed drivers. I achieved that after a couple months of playing and stayed there for nearly 3 years while playing 3-5 times per week. As a direct result of following his advice for two years and only playing 0-2 times per week when it's nice out I threw my first 350' (measured on a football field) golf shot with a putter last weekend.
There are roughly five groups of posters at the DGR forums: those in my situation, people who are new and are following the adivce, those that have followed his advice and get fairway drivers out past 400', those that throw far naturally and have a hard time coaching others to do the same, and those that choose to ignore his advice because they follow the "whatever works for you" philosophy and complain about hitting a plateau at 300'.
I'm giving advice to keep people out of that last group, but most of what I see here are people arguing that they want to stay there. Believe what you want, but that really is the result I'm trying to get by posting this stuff. Again, the purpose of these arguments I've been in has been to help pepole improve by pointing out common falacies that prevent people from reaching their potential. You can argue all you want and throw out all sorts of comparisons, analogies and chiches, but I am backed with results and none of that other stuff will change my mind.
If people don't want it, I can stop. Just say the word.
