Hello.. Nah, not really.. Looking at the small pamphlet as supplied with reels in those days, it states, St. Aidan first: DT9 + 120 yds, WF9 + 240 yds. Marquis #10 will sport: DT9 + 50 yds, WF9 + 175 yds. Capacity with a DT8 line is not stated for the # 10 reel, I´m afraid.. Yours borano20I want a reel for my Meiser 4/5 switch rod, and I use a 7wt. Airflo 40 Plus line. I heard the St. Aidan holds about 100 yards more backing than the Marquis 10 with a 8wt. DT line. Does this sound right to anyone.
