I am/was the lucky next recipient of Abe's Pass Around Tuktu. I totally agree with everything that's been said about the looks, fit & finish, and performance of this bow. John is right, you won't be disappointed with a Tuktu EX!!!
The carbon arrow that is supplied with the bow was the standard I used for testing my wood arrows (I can now say I have shot a carbon arrow, but I still prefer wood). The bow is set up for that arrow and I tried different arrows until I found the one that matched its flight. I tried spines from 50-55 to 70-75. I believe the lighter spines could have been tinkered with to shoot well, but I didn't want to change the tuning of the bow.
As Wooddamon found the 70-75 spines shot the best, matching the flight of the supplied carbon. Next best was 65-70 spine that looked to need only a nock height adjustment. My wood shafts all have 160 gr field points on 28" BOP shafts, with 4 5" shield cut feathers. The carbon weighed 586gr, 65-70 chundoo weighed 600 gr, and the 70-75 ramin weighed 680 gr. The EX is 54@28, so all shafts are in excess of 10 gpp.
Out to 20 yards, there was little difference in point of impact, not enough to worry about. At 25 yards, as one would expect, the heavier shafts started dropping off. All shafts were fast and hit with authority.
Thank you, Abe, for giving us the opportunity to try your bow.
