Personally, I think the Respect Pearl is really similar (especially if you go with a higher VAL angle and mayble a slightly stronger pin position. The Melee Jab is a great ball as well and I don't think you can go wrong with it.
If you are looking for another Marvel Pearl, I have one for sale. It does have a hairline crack near the fingers as well as a cracked beidge, but they could be plugged without a problem. Looking for 50 plus shipping. The cover is in good shape. I just can't strike with the thing lol.
