Do you mean a single line for pulling the tack out & then hoisting the sail? These systems do have some additional resistance, but not that much.
A big factor on my Tornado seems to be where the snuffer opening is placed along the pole...depending on the retrieval patch locations on the sail, you want the sail entering snuffer opening before all 3 (or 2) patches jam up together. Having the opening as close to the forestay as possible was a disaster...the sail would be a huge blob of clothe drapped over the opening...making lots of resistance to enter the ring. Placing the ring 12-18 inches forward allowed the sail to start entry prior to all 3 patches bunching up fully.
