You are admittedly new(ish) to conlanging and have created a nonstandard system.
It is better for beginners to use the standard for a few reasons:
1. It is used by the majority of forum users and professionals. (Unlike 'HPA' which is used only by you.)
2. There is a lot more support for learning the standard. (As far as I know 'HPA' has none. It is just a list of symbols.)
3. If everyone starts using whatever system they make up it will be even more confusing to learn.
If you want to pimp your system, do so in the thread for it, not in a thread for helping new conlangers. But you have yet to cultivate any real support for 'HPA' so I wouldn't get too excited.
point taken he can atleast use both... but IPA primarily
