Re: 10' 4wt Quickline
Nice job! I recently completed a 9' 5wt quickline rod; it is very light and quick.
For what its worth, I put a lightweight Orvis BBS III on it and found that it seemed to cast better by overlining it with a 6wt Rio Gold line.
Also, i am in the process of shaping up a handle for a new rod and was interested to note that its shape will be very similar to yours. It seems to be a full wells shape with the back sanded down. Great minds must run in the same channel!
