Layton, I find that SMB in the 8-10 inch range cost about $5 each when delivery is figured in. Actually, my HSB also cost that much after delivery was figured in.
A mental problem we have is that on the bass fishing tours, a bass is a bass is a bass. No more credit is given for a SMB or a spotted bass than is given for a LMB. Obviously LMB grow larger and so SMB and spotted bass are penalized just because then tend to be smaller.
SMB tend to be a stream fish just the same as spotted bass are. Hence the need to mimic stream conditions such as a gravel stream bed.
