Sticks

Ok, thnx.

ok I guess its 135/17..

Can someone tell me the best needle for the Seiko STW-8B ? The person I bought the machine from told me to use 17/231 needles. However google told me 135/17 or 16 for leather. Im a bit bit confused . Ill be mainly using bonded nylon 40s (#69). Also I only seem to be able to find 16/231 not 17. thnx
