I have been trying to search for some info on RDs. I'm looking for an upgrade from my 1730. Yes I am way outdated but honestly that thing has been GREAT! I've read this forum enough to know the V1, STi etc. are top dawgs and not really looking to argue the fact, however i'm not a huge speedster "all the time" and really do no more then 15ish when i do. With that being said, could i be directed to a thread or just get a lil help in this one on what's the better RD? Is the Pro 68se REALLY worth it or coming from the 1730, could I make do with something like the XTR-265? Also would anybody have any charts on these Whistlers to show the different options each on has or know where to find something like that? FWIW I've been lookin at XTR-265/330/540 etc, Pro 73/58/68se etc.
