i got my ambassadeur 550 in the mail today. the size seems to be between a 4600 and a 5000(probably closer to the 5000). it is a great looking reel. i don't think that i would trust it for bigger flatheads(30+ lbs) and blues(30+ lbs) but it would be a great reel for channels. it hasn't got the line capicity specs on it but i would guess 200 yrds of 12 lb test. i will probably try it out this weekend. i will update when i try it out. i just thought that since alot of people don't know anything about them i would put some info on. i know that the boc likes to cover as much info on equipment as possible.
