VKSlusny or the Space cowboy?

Which one should i get? Which one spins longer and is more stable? And would they both work for 1a and 5a?

My advice would be to look 10 threads back from the one you just created.

Yes, they would both work well for 1A and 5A. For what it’s worth, someone on YYF’s ask.fm asked a similar question;

Q: please answer this honestly between vkss and space cowboy: -which has the longest spinning? -which is most stable? -which is the smoothest?

A: Cowboy first.
