Handle sizes are the same, just the paddles are of the larger TE variety.A bearing switch to 3 ABEC7's (ends of spool shaft and the spool bearing itself), WILL enhance performance on the smaller baits. What works even better though is "Super-Tuning". Email me for more info on the "super-tuning". I have 2 Cardiff 300's that have been "Super-tuned" and the larger paddle handles installed, and they're just a step below my 300TE. Thanks and God Bless, Nicholas nshinkle@adelphia.net
