      Your rubbers are probably too long.with the pulleys system the pulleys are limited to 1/2 the travel of the rope you pull too load it so too get maximum omph you would need to measure from the notch of the spear to the back muzzle then 1/2 that for the pulleys travel then divide that by (3 - 1)(for 300%) or (3.5 - 1)(for 350% and so on)
      1200mm length from notch to back muzzle would be
      1200÷2= 600
      600÷(3.5 - 1)=240
      240 is the length of one rubber with 350% elongation

    Great video. I have an MVD carbon 120 inverted roller. There is no way to remove the pretension on the 1st band for storage. There is already a hole to the handle that I could open up a little if I needed to. Where can I get A-line anchor or a threaded bead?

    You never do reel line like this on the reel lol. The knot will be either pulled through or the barrel will break from any decent game fish

    Meandros handle fits correctly with the track of the tube? Higher lower or both the same height?

    • @castandspear

      We'd have to ask Kory. This was a custom handle he made, but I believe it was flush.

      DM @mr.californ1a on IG, he's always experimenting with bands. He'll have some ideas on what you're working on that might be better than this specific gun we discussed
