It's a marketing hype that is a total lie. I don't care how good the arrows are, I'm not giving my business to a company that uses snake oil marketing.Don't buy into the marketing of those shafts. I shoot Maxima Hunters but not because of the mythical "dual spine, weight forward" technology. There is no dual spine and there is no weight forward. It's been tested and debunked. Cut them as short as you want as long as you're spined correctly and you'll be fine. Here's a link to a thread about it from 3 years ago. Watch the video and then decide for yourself. Personally I don't care how they market them. I think they are good arrows but just not for reasons they explain on the box.
You won't get anywhere near 400 with the Blue Streaks. Maybe with Easton Axis 400s. The 250 (actual spine deflection of .417) Blue streaks are 7.4gpi. 26 x 7.4 = 192.4. Add 125 for your point and 40ish for fletching nock and insert and your still only at 357gr. If you want an arrow that short, to weigh over 400, you need a heavier gpi arrow or you could use a stiffer spine and get a weighted insert. Something like a 340 spine with a 125gr point and a 75gr insert would hit like a truck and fly really well.Thanks for the all the help and links. I need a spine between 380 and 420. I plan on using 125 gr bh, so with that short (26) of a length, out of a 58#, what would you all suggest? I contacted CE and he said the reds would not be good, to go w/ the blue. I'm open to all arrow choices but would like to have a finished weight over 400, if not over 425.
