Hello. I've recently switch from TBG to GZK 0.66 green. I'm very surprised because the GZK seems to strech less than the TBG. I've a 80cm draw and I cut it to 15cm (plus 2 cm each side for tying) tapered 25-20mm for 9.5 ammo. No problem with the TBG. Smooth draw. But The draw is much more heavy with the same setup in GZK green. For GZK do you use the 550¨% elongation or do you recommend other one? Sorry for my english, i'm french
. Many thanks for your help
