Re: a way to train your self with fly casting?
The Wulff Fly-O's we purchased were actually a bit lame. The yarn had no mass so you couldn't feel the rods load and a few double hauls rendered the yarn line useless! Thank goodness the Fly-O came out though or else we still might not have tools like that to work with.
During a fly show set-up day we got a chance to try the TFO prototypes of a MCR. These we liked. Because the blank was matched nicely with the line they performed very nice. You could do most any cast with them including roll casts on carpet and you could really feel them load.
The used a thick, hollow paracgute cord-like main line with doubled then single yarn as the leader/tippet.
I'll be using them Tuesday night for an indoor casting class for our club and have no reservations doing so. The thick, colorful line makes seeing loop formation very easy and the relatively slow movement of the line also helps in that.
