Just shoot him another email he may have missed your first one, he’s a busy guy and most likely gets a lot of email so it’s not hard to miss a few sometimes. He will most likely see this post and get back to you anyways now.
I had a PT wheel build by him it’s been really good I have trued it a few times since but that me and I have the stuff to do it, I like my wheels very true, I have no complaints on his build price was fair also.
Depending on how busy he is it can take a few months to get so if time is really important well, but if you are patient and want to give him your support have him build your set.
