I don’t post much but I think I know what yu are asking here.
1.Both these yo yo’s are close in specs.,only buy both if you want to compare them,or just want both.
2.See answer #1(Stock,in the hand of equal players you’ll get about the same spin times)But if you are asking this question the straight answer is no.
3.Yes a 10 ball will fit.
4.No.This is probally ONE OF the longest lasting response systems out there.
5.flowable silicone,the 888 sized pads,and you can even put O’rings in for more response.I put O’rings in when I was having trouble binding.They served the purpose.
6.Well this one I can’t answer.I haven’t done any YET.(the questions you are asking tells me that you shouldn’t worry about it and this should not be what determines which yo is good for you.)
7.These are hard tricks for a beginner to be worried about.Trust me you’ll be able to answer this question yourself before you need to know.
8.A 10 ball is a good bearing.You will have to clean it or play it a lot for it to spin longer than the bearing that comes with the legacy because legacy bearing comes cleaned with the yo yo.The 10 ball is almost always very responsive when you get it.
