Yes, SX mast and tiger main. Running a spin as well. The tiger main really changes the way the boat feels, its hard to get used to. I've been rotating the mast more and more to get what seems to be the right shape and the tales to flow on both sides. Have tightened the diamonds to 500lbs to get some pre-bend. Think the comptip is bending too much, squaretop seems disturbed. Have installed tell tales on the lower portion of the main but as of yet not been back in the water.Thanks so much for the great advice from all. Are you all saying that boat prep is not important? Shouldn't it at least be cleaned and waxed? One last question, mast rake for light winds- what do the tigers do? Mine is back, second hole from bottom on forestay adjuster. Forward rake requires repositioning of spin pole height on my boat.
