well i tried the dynema route on shooting lines, it used to get chaffed up on the spear hole where you tie it up, to the extent that the line once broke as i shot and the spear could have hit someone... i also find the thin dynema harder to handle underwater especially with gloves...my C4 was rigged with dynema and i didnt like it i switched to mono. i do acknowledge the points about memory and breakages,but i never got to experience it with the 1.6 or 2.2mm dynema ( which i normally use), maybe on the thinner ones...
cheers
