Funny that in the fly fishing world a low "start up inertia", which would equate to line creep if set under tension, is the gold standard in fly reel drags and high start up inertia is equated with a sub-par, "grabby" drag. Mooching reels are essentially beefed up fly reels, so shouldn't be a surprise that the high end reels with drag systems based on the best from the fly fishing reel (a la Abel Reels, Islander) have low start-up inertia and thus line creep if set on the light side.
Personally I'll take the butter smooth and consistent drag of an Islander every day over the alternative, even if it means tightening up a bit and then backing off once popped outta the clip.
Cheers!
