I have 2 Lexa Winn models with power handle, one 300 and 400. Both have the same issue with the thumb bar needing to be lifted manually. I found an old thread about it online (BD, I believe), that attribute it to a bad design on an anti-reverse lever spring that Daiwa never fixed. Regardless, they feel great otherwise and have performed well . 300 had no issues with the thumb bar until 2 seasons of heavy use, but the 400 was bought on a forum and had issues immediately.
I did get a 301 Tranx in low gear (had to buy power handle separate

) for inshore. I got 2 spools for fluke(15#) and blackfish(50#) and I really like it. I think it will hold up better than the Lexa's long-term, but only have about 1 season on it so far.
