Yep, initially tried 1:2 purchase and was too hard to pull out..... Now 1:1
Also have 1.5 mm lines running under the tramp to 3 locations to trip the tackline cleat. Will take some pics soon and post.
I'm definitely interested in seeing your set-up. Robbie put something similar on his last Cap (they keep selling out from underneath him) and I'll be doing the same over the winter. No change to the stock 1:2 single-line set up until after I get through Nationals and our Championship Qualifying event in November.
