Hi Sergio,
I'm down in Brantford, outside of Hamilton. That Tip of your friends is a true piece of eye candy! Do you have a larger pic of the riser- I have not seen one that had the curved accents befor, and must admit I did not know that this was an option. I'm about to order a Border Reiver, but now you got me thinking I should slap a deposit on a 4th tip. You're a bad influence!
JGoemaat- as for the wood in the center bow, the riser is walnut dymondwood I believe, but the limbs look to be a stained tiger maple. Just guessing though, as I bought the bow second hand, and am not really up on my woods.
