Just bought and installed new strings and cables on my 70 lb Mathews FX (Zebra). I have a 29.5 " draw. When " maxed out" , I am only getting 64 lbs. I had the cables twisted by the dealer - only to achieve 65 lbs max. The dealer said that because I had a 29" draw, I was losing 5 lbs. Personally, I think it' s BS! I know people who have a 26" draw and their bow draws at 72 lbs. I told him to check the cam position (as recommended by Mathews) - he just looked at me funny and told me that the cam never goes out of position. This is the only Mathews dealer within 100 miles. THe strings are the correct length. Any suggestions?
