as for westheman's issue can't say it's been a problem for me. they have their "quirks" though. LMII is in california, and i'm in new york state. every order has taken them no more than 2 days to be shipped, and of course ups ground is 5 days to here. admittedly, i don't like buying from them overall, but i don't let that stand in the way if they have a "better" product.
specifically i like that flat bar type rod because i don't like the idea of a single point of contact, the arc of the top rod, on the hotrod style.
second negative with hot rod is the larger area under the nut (neck/headstock joint) that has to be milled out to accomodate the larger brass chunk. in my opinion, this area of the neck needs to have as much wood as possible to maintain structural integrity in the even your guitar falls over or some other even occurs that might otherwise break the headstock off.
my opinion is unbiased as to the 2 companies themselves. my choice, is based on experience with both types of rod.
it's all opinion here....
