String length for an AFB

[Raedwald]

Now, here's one.....

The serving on the string for my Viper AFB is starting to fray, and with our 3D next weekend and little chance to shoot in a new one, I thought I'd re-use one of the old strings from my t/d recurve. Both are AMO68", both are Dacron, so, I thought, no problems.

Being the sort I am, I checked the string lengths first, just in case.

So, here's the question,

Should a 68" AFB use the same length string as a 68" recurve. Because the string that came with the bow is at least an inch, possibly 2, longer. Was this a "manufacturers rising chicken" or is there a genuine difference and should I be looking at a longer string?

The usual rule of thumb (&, I believe, AMO standard) is bow length minus 3" for a longbow/flatbow & minus 4" for a recurve. That'd explain your difference.

Thanks Rob - usual sound advice, much appreciated.

My 66 inch flatbow shoots best with a 62 inch string. That's a difference of 4inches.
