Has anyone run the Andrews TW55 cams? For what I can tell they are pretty close to the specs of the Woods TW-555 for about $100 less. Was about to pull the trigger on a set of Woods but for the price difference, is there much of a performance difference? I'm not real knowledgeable when it comes to cams, do the few degree differences make that much of a difference in how they work? Would a 4* key bring the Andrews closer to the Woods specs?? Thanks.

I'd contact Woods, and Andrews and talk to them . I read somewhere that Andrews actually grinds the cams for Bob Woods . Don't know if that is true or not . But I would bet that they could explain everything to you .

 

i here good things about those woods cams, i have andrews 37 in mine,go good,lumpy!
