I've helped get several folks started shooting traditional equipment. The most important aspect is consistency in both form and equipment. I try to start folks out with a 40lb bow, one that they have complete control over. Once they get proficient i realize they are going want a new bow. My goal is to keep them from going too heavy. Too heavy leads to a breakdown in form and eventually panic issues.
I believe changing types of bows, especially going from a recurve type grip to a straight longbow grip will cause issues. I understand TP is a mental issue but for those that have it, it is very real and frustrating. Very few folks can jump from bow to bow successfully and remain consistent. Most of us would be better served to stick to one bow or at least one type or style of bow. Howard Hill and a few other solid shooters may have changed bows often but they were the same style bow just different poundages.
I've used a clicker and know several guys that are incredible shots using them, Allen Shafer is one of them. But they are not always the answer, clickers are hard work. Allen will tell you it takes him several weeks to get use to and comfortable with a new bow, despite having a clicker. Again pick one style bow, a poundage range and consistency will follow.
