Yep, the handle would be very difficult to replace. Depending on the rod, you can save $100-250 per rod and there are lots of blanks (pac bay, batson, tiger eye, etc) that are not avaialable (or at least not advertised as available) through major rod manufacterers. Now that I've gotten into it, I realize that rod manufaturers sometimes cut corners and the fit and finish on some rods leaves something to be desired.
I don't have any more pictures of value from my first build. Check out this link though:

I used Art Schecks book, too and well as a flexcoat video in addition to seeing lots of. Be careful, though, rod building can be very expensive........
Anyway, back to the thread, the diamondglass is the latest effort of mine to find the perfect small stream rod....looking for something that is slow, around 7', loads easily at short distances, and roll casts well. From my intial trip with this rod this AM this rod seems to fit the bill. Had a bit of a comparison test at my local blugill pond this AM with some friends comparing to a 6'6" 3wt G. Loomis GL3, 7' 4wt Orvis Superfine, 7 1/2 ft 4wt Winston IM6, 6' 6" 3wt Scott V2 and this rod. Definitely harder to cast long distances with the fiberglass, but it met of exceeded to ability of the other rods at the other tasks, and was the best of the bunch at turning over flies at short distances.
