I had 2 marvel pearls, and just drilled an Idol Pearl. I had good success with the Marvel's out of the box, but both were a lot more condition specific than I wanted. They tended to burn way too fast off the end of patterns unless I could find some hold area.
Idol Pearl with similar layout to my last MP has a much different look. It is still rolly, but moves much stronger off the end of the pattern. I honestly havent thrown it a lot yet, and not tried it on any flatter patterns, but I think it will be a nice compliment to my Hyroad Nano, and more useable than the Marvel on a wider variety of patterns.
Idol and second MP were both lsyed out similar, pin down, 4 in to pap
