I just ordered M1P5S03-6J Black so once I receive it I would be interested in a group test even if only a few people sign up.

I have never orchestrated a group test but if enough people would like to test the: RT-15 M1P5S03-6J RT-30 M3P0S03-6J Let me know. If someone with experience is willing to lead it, that works too.
