Yes, I'm using the drill method vs slot. Once the front section is complete, I'll do like you suggest by twisting the rear loop tight after pushing it through the tail.
I'll try to keep the joint "V" or concave/convex vs flat shaped to get the most knocking.
I think it would be difficult to seal, paint & epoxy after assembly, so we'll have the final finish completed & then epoxy the rear wire harness holes.
Thought I may have a shot to fish for your awesome pike about 7 years ago while working the Tar Sands refineries north of Ft Mack, but the massive wildfires chased us out, no chance to fish. Those fires also pushed me into retirement = lots more fishing time here on St Lawrence River
Thanks
