I think the best on the market are the best ones that work for you... For me they are as follows because ive used them and had great results doing so.. NAP Spitfires/Muzzy MX3/Steel Force and Magnus 2 blades...

Ill be useing Steel Force Saber Tooths of of my Stealth
And bobbling the idea to use rage 2 blades or stick wiht spitfires on my Mathews
