RE: rest clearance
nodog,
The lightest 4" I've checked is the Duravane Low Profile at 6.5 grains. Thought I told you that. That's one of the reasons I went back to vanes for mu hunting arrows. Being a speed freak all these years and shooting feathers I just couldn't go back to vanes till I tried these. I know the latest rage these days are the Blazers, but I shoot a Martin with the X system and need to stay narrow for cable clearance. I could put the longer axles in but there really is no need at this point. I'm not going to quibble about the 5 grain difference between 3 Blazers and 3 Duravanes.
I know it may sound arrogant, but I am my own handyman. With few exceptions I'm the only one who works on my stuff (anything). On bows I do 100%. I like to get a new one and set it up rough to chrono it for curiosity. Then I tear the whole thing down and throw it on a pile in the floor. After I micrometer every little thing I put it back together and "go to work" on it. That's how I've learned what I have after shooting these stupid wheel bows for almost 33 years. And I made my share of mistakes during that time. And with technology the learning is never done.
The one thing that has helped, which yougsters should learn, is to take digital pics of the bow before any disassembly. Especially the cabling. I had a hard time with this on some single cam bows till I learned to draw pictures. Hey, live and learn.
I like an old adage. "The person who never made a mistake just never tried anything".
