I use Spider for all my big game leaders. Mostly 6# . I have very little problem with the no stretch. For a lighter color leader I'll use Mono & add just one length of 6# Spider wire or Fireline Crystal in the leader to increase the strength. With a 3-2-1-1-2-3 leader made from 2# mono it gives me the safety factor I like. I've caught Salmon, Bluefish, large Trout, Bones, & Bass on them with no problem. I add a ring or a swivel sometimes & I taper down to 3X & then down to 5 or 6X for trout. I usually make 5 ft. leaders & they will turn over at least their own length or longer of tippet. I do power furl & let the leader furl on the board & then re-furl pretty tight to get the final tightness I like. I usually twist until failure to get the max twist for any given material with selected weights & from then on, when I get that length of twist, I put the two butt ends on the center (reverse) hook, let it furl naturally & then power furl up quite a bit further, 4-5"'s or so.
