Lots of info in that post that I will leave for others to comment on. To answer your direct question, I have a few regular Providers that I see...2 completely UTR. I hobby 2 to 4 times a week. I seldom venture out of a small circle of Providers, though I am planning to see 2 new to me/established to you Providers now that fall is getting here. Both of you beautiful ladies know who you are.
That's the way I hobby. It works for me. I am certain others do it 180 degrees opposite and are quite happy with their results. Both, and anything in between, are perfectly ok. The only wrong way to hobby is to not hobby at all!
PS I would add that the 2 UTR's can't provide a reference for obvious reasons. I am thinking I should get a P411 account.
