Ok, for those who want what I consider a solid slider set, please try these:

I've spent COUNTLESS hours tweaking these and they seem to be ok right now. Keep in mind, this is on HOF difficulty, so they are CHALLENGING, but fair. By fair I mean the CPU won't just smash every strike and the CPU pitchers won't literally paint the corners all day. You need to be patient and work the count in your favor, don't be afraid to take borderline strikes. Please let me know if anyone uses them and if you have any suggestions or comments. Thanks!
