What drove me to purchase your tubes is their texture; they are not completely smooth like most.  I got one pack of the green-pumpkin and one of the green pumpkin copper, both in three and a half inch.  The smallies that inhabit the western portion of the Susquehanna river near Williamsport, Pennsylvania loved them both!  I've included a picture of just one - the biggest one of course - of the many quality small-mouth bass I caught.  Thank you for making a great product.
