I think that there is alot to be said peices with figure that is not "perfect" and in fact nature is not perfect in itself so it can throw up the most beutyfull natural creations in the likes of of figured maple and the such.
I have found that quite often when people pick through my piles of sycamore (great maple) they find the irregular peices the most pleasing to the eye.
i would love it if this was the case all the time but many people will only except the typical figure and color.
if people were more excepting i could offer some wonderfull high figure sycamore that has discolored to a pinkish brown color for as little as £5 a set.
but the fact is people wont buy it even at that price becouse it does not conform to what they are told they should expect from a given species or figure type.
for example the set below is has some really pretty figure but its uneven and the grain on set is not 100% streight also it has a band of discolor.
for this reason i will sell it for £25 instaed of nearly £80 for the first set.
apart from that it is quarter sawn and will make a stunning om or smaller guitar.
here is a close up of the figure,
i think the figure on the set you have displayed above is two types of figure on top each other.
the first is a diagonal deep curl that is simalar to ribon figure on mahogany of sort and the second figure is standard tight curl but very sparce and irregular.
these combine to create a another type of figure all together.
you get this alot with satin wood and sometimes walnut, mahogany and cocobolo we call it bees wing figure and its the result of two contrasting figures in top of each other.
It one of natures anomaly,s and all the more beutyfull and rare becouse of it IMHO.
If you want figure like this i suggest you buy from the mid grades and pick through stocks in person if you can becouse this type of figure is allmost impossable to photo.
any of the uk suppliers and some our own sponsers can supply this for you and i encourage you to shop around to the peice that is right fro your prodject.
I hope this has explained how we go about gradeing sycamore and at least awnsered your origonal questions.
Sorry for the rant,
Joel.
