thats what one would assume, but after getting my primo as a gift and using my friends superstar, i do have some notes.
the superstar is faster. not floatier, faster. for me, i found the wait distribution really helped it move on the string, and so did the shape. the primo, although lighter, played very flowy to me, kinda like a non-floaty punchline. naturally i like speedy yoyos, so i like the superstar more in this respect, but my friend liked the primo more.
in terms of feel, they both have that high quality YYF feel. the stability is what i found the most interesting. although you would think the hubstacks on the superstar would make it more stable, i found that the primo tilted less in long combos.
both had good binds.
these yoyos are really just different versions of the same beast. if you like large throws, i think you actually might enjoy the different feel and speed of the primo. the stability is very nice.
Thanks for the extra input. Very interesting to hear a comparison with the Superstar as I'm very familiar with it. You are correct on the hubstacks being detrimental to stability. I've taken the hubstacks off of my Superstar and Skyline. Removing the hubstacks makes them play surprisingly better. Lighter feel, smoother, more stability, longer spin time....hubstacks just need to go away in my opinion.
