At 10,000’ here I am spinning 8350-8450 with the s-58 weights they weigh in at 58.9 grams on my scale
S-60 weigh in at 59.7 and I spin at 8150-8250 max
All at 10,000’
Take your current weights out and weigh them on a gram scale- then at least you know what you have- I have seen them all over the place
I don't see a S- 59 gram weight for the adapt ( Country Cat in Link below) What's you part number on your weights ??
