D-10 is only slightly stronger than '97--to the point that BCY took it off their list of products. The same basic material is available as Force 10 x-bow material.
Dynaflight '97 is SK75 Dyneema. 10 is SK78 Dyneema.
If you want a significant increase in strength, move up to 8190, which is SK90 Dyneema. Much smaller diameter, my choice for a "skinny" string because you don't have to go with a low strand count. It's about 1/2 the diameter of Dynaflight--18 strands is still a small diameter string.
A Dyneema/Vectran blend like 452X or Trophy will be the most stable, but will fuzz up some.
