Unfortunately the TW learning center no longer keeps data on the ncode and kfactor versions. However, the BLX six one 95 is extremely low powered. So much so that if you were looking for something that was even more low powered than that, it begs the question: why are you looking for such low power? Do you have difficulty keeping the ball in play? It really doesn't get much lower than that.
I would stick with the blx six one 95, since it's in current production and easier to get multiple copies of it (and matched for weight and balance). you'll be hard pressed to find 2 or 3 ncodes or k-factors that are better than a 7/10 in condition, let alone get them with similar specs.
And, I'd also recommend stringing it up with full bed of poly @ 56 lbs. You can pretty much swing for the fences and keep it in play, no problem.
If you have to go syn gut, I wouldn't string less than 64 lbs.
