I'll try to do this without blasting a brand ! I don't like expandable thats me ! i know lots of people that are very happy with them ! yeh for them ! montecs are trash out of the box until you sharpen them . I got them i know. muzzy I use them now they also sometimes get dull but will blast through a deer with a little sharpening. slick trick they had issues last year but now their really sweet i hear ! sharp out of the box . I will be shooting slick tricks next year for sure !montecs i read make a whisle sound when going through the air . I never shot them enough to notice. I will never hunt with aluminum arrows again ! why would you change IMO your taking a leap backwards.
