If you search the threads, there was a recent one about random settings and the variety available. You need to read more than just one though! You might check out a few people that sound pretty relieable and in the same sphere as you and check their postings and threads! The answers are there and it is a lot easier to ask a question looking for answers. But, when you do the research, you learn a lot more!

And generous input! As per my discovery!:jointsmile:
